The Diamond Effect: How Pressure Transforms Our Lives
When my toddler Henry disappeared during a water gun fight at our family cottage, I experienced a parent's worst nightmare. As I frantically searched the shoreline, haunted by visions of finding his little body floating under the dock, my body went into full pressure response-pounding heart, racing thoughts, overwhelming emotions. Those terrifying minutes before finding him safe on my sister's deck taught me how pressure manifests in both mind and body. This experience became the catalyst for my exploration of pressure across human experience, from Olympic athletes to military leaders, from cancer patients to corporate executives. What I discovered was fascinating: pressure follows predictable patterns, and our responses to it determine whether it crushes us or transforms us into diamonds. The Power of Pressure has become a cultural touchstone, praised by figures ranging from Toronto Raptors coach Nick Nurse to Harvard professors, precisely because it reveals how this universal human experience can become our greatest ally rather than our enemy.

Understanding the Pressure Equation
Pressure is distinct from related states like stress or fear because it requires action. While watching a beloved sports team creates stress, playing in the game creates pressure. It's not just caring about the outcome but having the ability to impact it. When I asked over 1,000 people about their highest pressure moments, their responses spanned the full spectrum of human experience-from Olympic competitions to active shooter situations, from single intense moments to prolonged periods like caring for dying parents while managing careers.
The pressure equation consists of three fundamental factors: importance x uncertainty x volume. Importance forms the foundation-if something doesn't matter to you, it creates no pressure. What matters isn't the importance of the task itself but the importance you place on the outcome. Even mundane work creates pressure if keeping your job matters to you.
While importance creates baseline pressure, uncertainty dramatically amplifies it. Michelle Segal's story illustrates this perfectly-after her company's acquisition, management announced only 8 of 13 regulatory staff would remain, putting her in direct competition with her counterpart. The uncertainty made focusing difficult as she contemplated potential relocation and family disruption. Interestingly, with modest stakes, uncertainty can actually create enjoyment-like the suspense that keeps us engaged in novels or TV shows. But when stakes involve job loss or family relocation, uncertainty registers in the brain similar to physical pain.
Volume transforms pressure from manageable to relentless in modern life. Working with the Canadian Paralympic Committee, I witnessed this firsthand when executives identified 189 different metrics they were tracking-a staggering number of important, uncertain things demanding attention. When I ask workshop participants about their greatest pressures, "volume" or "lack of time" is mentioned first over 90% of the time. This volume permeates every aspect of life-balancing work with children's schedules, self-care with elder care, career success with meaningful relationships.
When importance, uncertainty, and volume collide, our bodies respond dramatically-racing hearts, shallow breathing, disrupted sleep patterns. Beyond these physiological effects, pressure narrows our attention, amplifies our biases, and diminishes our capacity for empathy, creativity, and learning. This creates what I call the paradox of pressure: our body's default response robs us of the very abilities that would help us manage pressure effectively.

Blood, Sweat, and the Brain: How Your Body Responds to Pressure
Pressure isn't an external force but an internal experience-two people in identical situations can have completely different responses. When we feel pressure, our bodies react in ways that often undermine our ability to respond productively.
The experience of pressure involves a complex interplay between thoughts, emotions, and physical changes. Dr. Penny Werthner, dean of kinesiology at the University of Calgary, has pioneered using biofeedback and neurofeedback to understand these responses. These tools reveal that pressure is both psychological and physical-not just a "mental" phenomenon as traditionally treated in sport psychology.
Under pressure, our sympathetic nervous system signals the adrenal glands to produce adrenaline and cortisol. This increases heart rate, dilates lung bronchi for more oxygen, inhibits digestion to preserve energy, increases sweating, and constricts blood flow to peripheral areas. Even elite athletes show dramatic physiological changes during simulated pressure-disrupted coherence between breathing and heart rate, elevated and erratic heart rates, and significantly decreased peripheral temperature as blood flow is conserved for essential systems.
While biofeedback shows the body's response, neurofeedback reveals what happens in the brain. Under pressure, most people experience an increase in high beta waves (22-38 hertz), indicating an overactive brain state similar to what prevents sleep. This creates a dangerous feedback loop: perceiving importance triggers physiological changes, which further activate the brain, leading to overthinking and performance mistakes.
Under pressure, our brain's sensory gating goes into overdrive, drastically reducing what information we process. This "attentional tunneling" affects us both externally and internally. Studies of police officers in shootings show 84% reported diminished sound and 79% experienced tunnel vision. Internally, we lose access to our skills and knowledge, as I discovered in a consulting interview where I couldn't recall basic business questions until the moment the elevator doors closed.
While momentary pressure primarily affects performance, chronic pressure creates more fundamental problems. Dr. Herbert Benson's research showed that continuously activated fight-or-flight responses lead to elevated cortisol, increasing blood cholesterol, triglycerides, blood sugar, and blood pressure-all risk factors for heart disease. Beyond physical effects, prolonged pressure can make narrowed attention our brain's default state.
Our counterproductive responses to pressure persist because evolution moves slowly. Our hardware evolved to optimize for safety, predictability, and physical power in acutely stressful situations-priorities for survival when hunting or facing physical threats. Creativity, information recall, and empathy, while crucial for modern pressure situations like presentations, weren't historically correlated with survival.
The key to solving the pressure paradox is recognizing that pressure isn't external circumstances but an internal experience we can change. Simple reframing techniques can transform our physical response-seeing a situation as a challenge rather than a threat reduces cortisol production, saying "I'm excited" instead of "I'm nervous" improves performance, and viewing stress positively eliminates its long-term health impacts.

Becoming Pressure Ambidextrous: Managing Both Moments and Marathons
Pressure manifests in two major ways: peak pressure moments and the long haul of pressure over time. While we typically think of pressure as momentary events, like Kyle Lowry's NBA championship game, pressure also comes in extended periods, as demonstrated by Olympian Jeremiah Brown's three-year journey from novice to Olympic rower.
Jeremiah Brown's unlikely Olympic journey exemplifies pressure over time. After watching Canada win gold in rowing, he committed to making the Olympic team despite never having rowed before. Moving across the country, he balanced a banking job with brutal 4:30 AM training sessions, eventually earning a spot on the national development team. Under legendary coach Mike Spracklen's grueling regimen, Brown endured constant physical pain-Krazy Gluing his blistered hands shut before training-and psychological pressure from fierce internal competition for limited boat seats.
Peak pressure moments have clear beginnings and endings. For Brown, the Olympic final was excruciating-fatigue setting in 48 hours before with sweaty palms, elevated heart rate, and shallow breathing. When the moment arrived, six boats lined up for six final minutes of pain. At 500 meters they were in third place, and with the final 30 strokes, they overtook the British team to secure silver. Unlike the long haul, when peak pressure moments end, the pressure immediately vanishes, replaced by either ecstasy or disappointment.
The skills needed for navigating the long haul differ from those required for peak pressure moments. Some excel at sustained performance but struggle in crises, while others perform brilliantly under immediate pressure but may not have well-ordered lives outside those moments. People who are "pressure ambidextrous"-capable of both performing in peak moments and approaching long-term challenges with commitment-become unstoppable.
The fundamental skill for pressure ambidexterity is creating space between trigger and response-noticing what you're feeling before acting. Most people jump from point A (thoughts/feelings) to point C (behavior), but high performers recognize point B-the moment where observation and choice happen. Under pressure, we often lose this space, becoming our anxiety or racing thoughts as the primitive brain takes control. What distinguishes humans is our ability to observe ourselves-to notice "I'm feeling angry" rather than simply being angry.

Connect with Why It Matters: Finding Meaning in Pressure
Stress and meaning are inextricably linked-we don't stress about things we don't care about, and meaningful lives inevitably involve stress. When facing long-haul pressure, meaning becomes a vital ally. The ability to connect daily actions to what matters most is essential, as pressure becomes debilitating when this connection is unclear. People who accomplish great things under sustained pressure are typically driven by strong purpose. As Jeremiah Brown reflected about his Olympic journey: "At the end, what you are left with is the answer to the question 'Why are you doing this?' And is that purpose strong enough to take you through inordinate amounts of discomfort and anxiety? Ultimately, it's about meaning."
Meaning isn't constant but happens in crystallizing moments-like when my infant daughter Stella experienced snow for the first time, laughing and grabbing at snowflakes, or watching my son Jack master parallel skiing. Even in deeply meaningful long hauls, we spend much time disconnected from meaning, handling mundane tasks.
Connecting with meaning doesn't necessarily create happiness. Rick Hansen's Man in Motion World Tour exemplifies this-after becoming paralyzed at 15, he dominated wheelchair racing before embarking on a 24,000-mile journey across 34 countries. The pressure was immense, causing sleeplessness and anxiety, with Hansen describing his experience using words like "despair," "anger," and "scared." Yet meaning prolonged his ability to endure. The peak-end effect explains why difficult experiences can be remembered positively-while Hansen's hour-by-hour happiness was likely low, the triumphant conclusion (raising $36 million, exceeding his $10 million goal) created a profoundly different memory than if he'd abandoned the journey.
While meaning is deeply personal, three fundamental sources provide it: growth, contribution, and connection. Growth gives meaning to pressure-when we believe pressure is helping us improve in ways that matter, it transforms our experience. Shaun Francis found the pressure-cooker environment at the US Naval Academy satisfying because it was developmental, while similar pressure at an investment bank led to burnout because growth wasn't prioritized.
The second major source of meaning is contribution. Rick Hansen's Man in Motion World Tour was fueled by his desire to create a world without barriers for people with disabilities. While most pressure periods don't have such clear contribution paths, the principle remains: when we feel we're helping others, our journey becomes more meaningful.
The final source of meaning comes from growing closer to others. Olympic gold medalist Rosie MacLennan experienced this during her difficult journey back from multiple concussions. After months without training and a series of setbacks, she found herself at the Rio Olympics with a competitor from China. In that moment of genuine connection-chatting, smiling, cheering each other on-she realized she'd already won her "internal gold medal" by simply being able to compete again.
To stay connected to meaning during long-term pressure, we need to establish an authentic line of sight between our daily actions and what truly matters. This process involves four interconnected components: North Star (what matters most), Vision (a clear mental image of your desired future), Goals (what you need to accomplish), and Daily Decisions (the small moments that determine your direction).
Chapitre 6
See What's Not at Stake: Gaining Perspective in Critical Moments
In peak pressure moments, the importance we attach to outcomes can become suffocating rather than motivating. Johann Olav Koss, Norway's celebrated speed skater, experienced this paradox before the 1994 Lillehammer Olympics. Despite being a world champion, he found himself crying in a hotel stairwell two weeks before competition, crushed by national expectations and his own fear of failure. Most paralyzing was his belief that Olympic failure would mean failure for the rest of his life.
Importance plays a dual role in the pressure equation. Over the long haul, importance provides the slow-burning energy needed to persevere through setbacks. But in peak pressure moments, importance can become overwhelming. For Koss, the Olympics' importance was essential during training but became stifling as the event approached. He allowed the stakes to expand from a speed skating competition into a referendum on his entire life's worth.
The first tool for managing importance is to refocus by asking: "What's NOT at stake?" This means identifying things in your life that won't change regardless of outcome-family love, friendships, health, financial security, planned vacations. Olympic gold medalist Rosie MacLennan makes listing these "anchors" a discipline: "The people who really matter in your life are going to be there regardless."
When this first step isn't enough, we must question our assumptions about what's truly at stake. During an anxiety spiral, become your own psychologist by: 1) Pushing for data ("What evidence supports that this is actually at stake?"); 2) Pretending you're advising someone else to gain objectivity; and 3) Giving yourself the benefit of doubt ("What value is there in assuming this is at stake when I'm not sure?").
Our egos often amplify pressure by making outcomes about our self-worth. Andrew Blau experienced this when leading Global Business Network during the 2008 financial crisis. As CEO, he felt the weight of the storied company's legacy, made painful layoffs, and tried heroically to shoulder all stress-which backfired by creating more tension. He eventually realized he'd mentally expanded the stakes beyond reality, making the situation a referendum on his leadership worth.
Manufactured urgency surrounds us-from booking.com's "last room" alerts to colleagues' high-priority emails. The Eisenhower Box helps distinguish between what's truly urgent versus merely important. To audit urgency, ask two questions: "What's the worst that happens if I act now?" versus "What's the worst that happens if I delay?" Sometimes immediate action is warranted (like a kitchen fire), but often waiting provides better outcomes.
Olympic hockey legend Hayley Wickenheiser's perspective forms a key technique for peak performers: while capturing an Olympic gold medal represents years of dedication, "it's just hockey." Most high-pressure situations involve financial or reputational stakes, not life-and-death consequences. Even in extreme circumstances with life-threatening stakes, there's benefit to accurately gauging importance.
Chapitre 7
Take Direct Action: Controlling the Controllables
When uncertainty is present, pressure follows. Research shows people experience more stress when facing uncertain outcomes than certain negative ones-participants were less stressed knowing they would definitely receive an electric shock than when facing only a possibility of one. For emergency physician Dr. Andrew Petrosoniak, the highest pressure comes not from hopeless cases but from those with uncertain outcomes where intervention might succeed.
Stoicism's 2,500-year-old philosophy offers wisdom for managing uncertainty through the dichotomy of control-separating what we can control from what we cannot. Between the extremes of complete control (our thoughts and actions) and no control (other people's thoughts and actions) lies the "uncertainty zone" where outcomes depend partly on us and partly on external factors. In peak pressure moments, focusing on controllables builds self-efficacy and reduces helplessness.
Olympic beach volleyball player Martin Reader faced immense pressure qualifying for the 2012 London Games. In the decisive moment of the final match, with Olympic dreams hanging in the balance, he focused on the one thing completely within his control: his serve. After months of preparation targeting the Mexican team's weakness, Reader delivered a perfectly executed serve that secured their Olympic berth. When under pressure, the essential question becomes: "What's your serve?"-identifying what is completely within your control in any given moment.
Dr. Petrosoniak's trauma team success begins with pre-briefing-scripting the first five minutes and reviewing key decision points before patients arrive. This routine creates alignment, control, and accountability despite inevitable uncertainty. Elite athletes similarly rely on routines: Brian Orser developed detailed plans for skating first, second, or sixth in competitions to manage the unpredictability of skating order.
Breathing is uniquely both automatic and consciously controllable, making it a powerful "beachhead of control" during uncertainty. The key is to "breathe low and slow"-about six breaths per minute through your diaphragm rather than the faster chest breathing that happens under pressure. This creates physiological coherence, synchronizing heart rate with breathing, promoting alpha brain waves, and dampening the racing beta waves of anxiety.
When Sean St. John was diagnosed with testicular cancer at 25, threatening his promising finance career, he controlled the one thing he could-his perspective: "Okay, life's been really good so far... This is what the test is going to be." While his parents nearly separated from anxiety, St. John remained remarkably fearless. Viktor Frankl similarly discovered in Nazi concentration camps that choosing how to view suffering was "the last human freedom."
HR leader Jenn Cruz faced a perfect storm of uncontrollable circumstances during a high-stakes reorganization announcement. After personally delivering layoff news that morning, she encountered catastrophic A/V failures just as 300 anxious employees gathered for their fate. Racing to find tech support, she got locked in a stairwell with no cell reception. This forced moment of pause became her salvation-taking deep breaths, she developed "Plan B" to move the meeting to another room. This moment of focusing solely on what she could control enabled her to successfully navigate an otherwise overwhelming situation.
Chapitre 8
Embrace Inevitable Uncertainty: Faith Amid the Unknown
Our brains evolved to respond to uncertainty similarly to pain, driving us to minimize it whenever possible. Yet trying to control uncertainty over the long haul can backfire, creating helplessness that only increases pressure. Instead, we must learn to embrace inevitable uncertainty while maintaining faith that things will ultimately work out.
Luc Mongeau's story illustrates the paradox of handling long-term uncertainty. After a meteoric rise at Mars to CMO, his career imploded, leading to five years of unemployment and self-doubt. Finally landing a CEO role at Weston Foods, he faced a perfect storm: his major reorganization collided with a massive price-fixing scandal that predated his arrival. As customers canceled orders worth millions, Mongeau's inner narrative turned destructive until a simple conversation with his HR head reminded him of Buddhist principles he'd learned during unemployment. The paradox became clear: staying energized during prolonged uncertainty requires simultaneously accepting that the future is unknowable while maintaining faith that everything will work out.
The problem with trying to control uncertainty is that we use the wrong tools. Melissa Quinn illustrates this through her experience integrating Monitor's hypothesis-driven approach with Doblin's design thinking methodology. While Monitor valued quickly finding answers among established solutions, Doblin valued exploration and deeper understanding before converging on solutions. Quinn developed a framework contrasting "business mindsets" (valuing efficiency, right answers, and risk elimination) with "innovation mindsets" (valuing exploration, right questions, and learning from failure).
The improv game "Fortunately, Unfortunately" reveals a deeper truth: not only is the future unknowable, but so is how we'll interpret present circumstances in hindsight. What seems fortunate now might later appear unfortunate, and vice versa. Christine Sinclair, soccer's all-time leading international goal scorer, demonstrated this perfectly. When I asked about her greatest setback, she rejected the premise that Canada's humiliating last-place finish in the 2011 World Cup qualified as one. "No one from that team quit; we rallied around the defeats... We weren't going to let that tournament define us." That loss catalyzed the team to win Canada's first Olympic soccer medal the following year.
James Stockdale survived seven years as a prisoner of war in Vietnam through three approaches: separating what he could control from what he couldn't, creating social support through a wall-tapping communication system, and maintaining unwavering faith in eventual positive resolution. The "Stockdale paradox" reveals that "the optimists" who repeatedly set specific deadlines for release ("We'll be out by Christmas") were the ones who didn't survive. Believing things will work out doesn't mean expecting everything to go smoothly, but recognizing that while the journey may be difficult, you'll prevail in the end.
Dr. Marjorie Dixon's journey exemplifies this balance between acceptance and action. As a first-generation Jamaican Canadian determined to revolutionize women's fertility care, she faced overwhelming pressure building her clinic. When her business partner withdrew financial support, construction delays threatened opening, and her landlord opportunistically raised rent by $50,000 monthly, friends worried she was "off her rocker." Dixon remained resourceful, securing licenses, hiring lawyers, and ultimately forcing builders to meet deadlines. Her clinic opened just one day behind schedule and now thrives as the innovative space she envisioned.

The Foundation of Resilience: Sleep, Nutrition, and Movement
When managing pressure over the long haul, physical wellbeing becomes essential. Phil Wilkins learned this lesson the hard way when, while building a new business unit for a financial technology startup, his exhausting schedule of travel and 20-hour workdays led to a seizure while driving. This wake-up call forced him to prioritize rest and recovery, implementing boundaries like leaving his computer at work, putting his phone away at home, and aiming for seven hours of sleep nightly.
Research demonstrates that sleep deprivation severely impairs cognitive performance. A groundbreaking study found that after 17 hours of wakefulness, cognitive performance deteriorates to the equivalent of having a 0.05% blood alcohol concentration-legally drunk in many countries. Yet while we'd never celebrate someone working drunk, we often praise those who sacrifice sleep.
Beyond performance, sleep deprivation has profound health implications. Emerging research links insufficient sleep to cancer, diabetes, obesity, and neurodegenerative diseases. Particularly significant is the discovery that sleep enables the brain's unique waste-clearing system, where cerebrospinal fluid flushes toxins including amyloid-beta (associated with Alzheimer's) from between brain cells-a process that only happens during sleep when neurons shrink by up to 60% to create flow space.
When under pressure, getting seven to eight hours of sleep is essential. No other single change will better improve your ability to handle pressure. But precisely when we need sleep most, worry often keeps us awake. Breaking this pattern requires keeping your sleeping environment dark and cool (65-68F/18-20C), maintaining consistent sleep and wake times, and developing a proper transition routine. Dr. Greg Wells recommends "defending the last hour" by eliminating electronic devices and reading physical books, preferably fiction.
Even with good sleep habits, anxiety before important events can keep us awake. Three practical approaches can help overcome pre-event insomnia: an elastic mindset (remembering previous successful performances on minimal sleep), the 100 Challenge (counting backward from 100 while visualizing writing the numbers), and the Breathing Drill (thinking "out" while breathing in and "in" while breathing out).
Food and water are our only inputs into a closed system that produces an astonishing variety of outputs. What and how we eat directly correlates to our ability to handle volume over the long haul without exhaustion. The key is viewing food not just as sustenance but as performance fuel that stabilizes blood sugar levels throughout the day. Going too long without eating leads to glucose depletion, making us more impulsive, punitive, and aggressive-qualities that undermine our ability to handle pressure. The secret to sustained energy is balancing carbohydrates and protein with every meal or snack, and selecting carbs with a low glycemic index (55 or less).
Exercise provides both long-term health benefits and immediate advantages when under pressure. A study of Austin firefighters showed those who followed a 16-week rowing program demonstrated reduced physical responses to stress scenarios-lower blood pressure and heart rate increases during simulated emergencies. Research consistently shows exercise reduces anxiety and improves mood, even for those without clinical depression. The good news? Just fifteen minutes of running or an hour of brisk walking daily provides these benefits-no need for intense training regimens when under pressure.

The Power of Connection: Building Your Support Network
When facing his father's throat cancer diagnosis, I witnessed how even fiercely independent people eventually need support under extreme pressure. My father initially insisted on driving himself to radiation treatments, but after weeks of grueling therapy, accepted help from his support network. While seeking support is vital for managing pressure, not all support is helpful. A poorly constructed support network can create additional stress by turning into a pity party, adding others' emotions to your burden, or unnecessarily raising the stakes.
Support networks can backfire in three ways: becoming pity parties that keep you stuck in negative emotions, adding others' emotional reactions to your burden, or raising the stakes on already important situations. Heidi Tourond's experience after her husband suddenly left illustrates this-while she needed to quickly find employment after 16 years out of the workforce to support her teenage sons, many friends wanted to commiserate rather than help her execute her action plan.
Despite the potential pitfalls of support networks, social support remains one of the strongest predictors of resilience and positive health outcomes. Studies of Vietnam veterans showed that homecoming support was the most significant predictor of PTSD symptoms, "superseding combat exposure, childhood and civilian traumas." The National Institutes of Health found that "the effect of social support on life expectancy appears to be as strong as the effects of obesity, cigarette smoking, hypertension, or level of activity."
To tap into the value of social support while avoiding pitfalls, three key principles emerge: keep your network tight (size matters), recruit from "inside the arena" (fellow combatants rather than spectators), and set terms of engagement proactively. The stress created by a support network is directly proportional to its size. Olympic swimmer Martha McCabe managed this by zeroing out her support network and selectively letting people back in with a new phone number.
Theodore Roosevelt's famous "man in the arena" speech celebrates those who strive and sometimes fail while "daring greatly" rather than critics who observe from the sidelines. Effective support networks rely on people who are shoulder-to-shoulder in the struggle rather than observers or bystanders. When facing cancer, both my father and Sean St. John found their greatest support from fellow patients who "knew exactly what I was going through."
While it may feel presumptuous to dictate how others should support you, the most effective support relationships have clear boundaries. Martha McCabe gave her family specific guidelines: "don't call me; I will call you." This wasn't rudeness but recognition that truly supportive relationships must serve the performer's needs rather than the emotional needs of the support system.
The most effective support under pressure comes from a small group who are: 1) "in the arena" with you; 2) not prone to pity parties; 3) able to put your needs before their emotional reactions; and 4) focused on what you need to do rather than what's at stake. Jim Rohn's observation that "You are the average of the five people you spend the most time with" suggests evaluating whether your closest circle meets these criteria.
Pressure gets an unfair bad reputation when in reality, it's impossible for most people to remain truly calm during highly important, uncertain situations. While your body will inevitably activate-heart rate rising, breathing quickening-this isn't something to fear. This energy surge can be better than calmness when properly harnessed. Pressure is what sets world records, fuels bravery, breeds persistence, and unlocks hidden strengths. Rather than seeking to eliminate pressure, we should learn to tap into it as a source of power when facing life's inevitable challenges. After all, no pressure means no diamonds.
