The Dance of Change: Finding Strength in Life's Inevitable Transitions
In a world obsessed with stability, Brad Stulberg's "Master of Change" arrives as a revolutionary manifesto for navigating life's inevitable disruptions. This isn't just another self-help book-it's a profound exploration of human resilience backed by both ancient wisdom and cutting-edge science. Since its 2023 release, the book has garnered praise from thought leaders like Adam Grant and Daniel Pink, who call it "essential reading for our uncertain times." What makes this work particularly compelling is how it challenges our cultural narrative that stability should be our default state. Through vivid storytelling and practical frameworks, Stulberg introduces us to a powerful alternative: rugged flexibility-the capacity to be simultaneously strong and adaptable in the face of change. Whether you're facing career transitions, relationship shifts, health challenges, or simply the everyday evolution of life, this book offers a transformative lens through which to view disruption not as something to fear, but as an opportunity for growth.
Chapitre 2
The Illusion of Stability in a World of Constant Change
We experience roughly 36 major "disorder events" throughout adulthood, yet our culture has conditioned us to view change as abnormal and undesirable. This fundamental misunderstanding stems from Claude Bernard's 1865 medical model and Walter Cannon's 1926 concept of "homeostasis"-the tendency of systems to resist change and maintain stability. While this model works for narrow cases like fevers, we've wrongly applied it universally, creating a cultural bias against change.
When faced with change, people typically respond in four counterproductive ways: avoiding it entirely, actively resisting it, sacrificing all agency amid chaos, or desperately trying to return to previous states. All these strategies ultimately create more suffering. Take Thomas, whose carefully constructed life was upended by the pandemic. His initial response-trying to recreate his pre-pandemic routine exactly-led to frustration and burnout as he fought against an irreversibly altered reality.
The late 1980s brought a revolutionary alternative from University of Pennsylvania researchers: allostasis, or "stability through change." Unlike homeostasis (order, disorder, order), allostasis describes a pattern of order, disorder, reorder. Healthy systems don't rigidly resist change but adapt to it, moving forward with grace and grit. Following disorder, living systems achieve stability somewhere new: X to Y to Z, not X to Y back to X.
This pattern appears everywhere: in evolution, where species adapt or perish; in literature's "hero's journey," where protagonists return transformed; in psychology, from Jung's circular self-transformation to modern therapeutic approaches; in spiritual teachings like Richard Rohr's "universal wisdom pattern" of order-disorder-reorder; and in organizational science's freezing-unfreezing-refreezing cycle. Even our relationships follow a harmony-disharmony-repair process.
The key insight? We achieve stability through change, not by resisting it. As Sterling notes, "The key goal of regulation is not rigid constancy... Rather, it is the flexible capacity for adaptive variation." Think of calluses forming on hands that lift weights, brains rewiring for focus after digital distraction, or recovery from depression involving moving forward rather than returning to a previous state.

Embracing Impermanence: The Path to Freedom
Tommy Caldwell's harrowing experience as a hostage in Kyrgyzstan transformed him completely. While climbing with his partner and friends, they were captured by armed rebels. After six days, Caldwell pushed their captor off a cliff to escape-an act that saved their lives but left him questioning his identity. Though physically free, he struggled to integrate this massive disruption into his self-narrative, becoming anxious and disconnected from his former self.
Change inherently causes tumult, but it's our resistance rather than change itself that causes the most harm. Harvard psychologists Bruner and Postman demonstrated this with their anomalous playing cards experiment, where participants struggled to recognize cards with unexpected colors. Similarly, subjects wearing inverted goggles experienced extreme disorientation until they adapted. These experiments reveal our natural difficulty processing unexpected changes.
Major philosophical traditions-Buddhism's concept of viparinama-dukkha, Taoism's dynamic path, Stoicism's dichotomy of control, and existentialism's acknowledgment of impermanence-all recognize this challenge. Modern science confirms that resisting change triggers stress hormones like cortisol, causing physical ailments.
Eighteen months after Kyrgyzstan, disaster struck again when Caldwell accidentally cut off his left index finger with a table saw. Despite three surgeries, doctors couldn't reattach it and told him his climbing career was over. Yet Caldwell quickly accepted his new reality rather than resisting it. "When I started climbing again, I felt a surprising amount of exhilaration. My focus and direction were crystal clear," he said, finding liberation in others' low expectations.
Erich Fromm's profound question captures this shift: "If I am what I have and what I have is lost, then who am I?" In his 1976 book "To Have or To Be?", Fromm distinguishes between two modes of existence. In having mode, we define ourselves by possessions and attributes that can be taken away, making us fragile. In being mode, we identify with our essence and core values.
Both Caldwell and Christine (a marketing director who lost her job during COVID but discovered her true passion for writing) benefited from what Harvard scientist Daniel Gilbert calls the "inescapability trigger"-we're more likely to find positive views of situations we're stuck with than those we can escape. Only when we fully accept we cannot change an experience can we change our relationship to it.
In his 1915 essay "On Transience," Freud argued that impermanence actually increases value: "Limitation in the possibility of an enjoyment raises the value of the enjoyment. A flower that blossoms only for a single night does not seem to us on that account less lovely." The philosopher Todd May similarly argues that mortality gives life meaning. To live is to lose, and the certainty of loss makes our experiences precious.

The Psychology of Expectations: Why Reality Minus Expectations Equals Happiness
In May 2021, after fifteen months of pandemic shutdown, there was finally hope as COVID cases plummeted due to vaccines and other factors. People began visiting homes of family and friends without worry. By early July, however, the Delta variant emerged, causing cases to climb rapidly. Despite conditions being objectively better than at the pandemic's start-with vaccines and therapeutics now available-people felt devastated because their expectations for a return to normalcy were shattered.
Our happiness in any moment is a function of reality minus expectations. When reality matches or exceeds expectations, we feel good; when it falls short, we feel bad. Research shows countries that rank highest in happiness often have citizens with lower expectations. The Danish, for example, report high satisfaction because their expectations remain modest, unlike Western cultures that promote constant hedonic happiness.
Recent neuroscience reveals the brain functions primarily as a prediction machine. The prefrontal cortex constantly generates predictions that are sent to the brain stem, preparing the mind-body system for what's anticipated. This forward-looking stance is evolutionarily efficient-without it, we'd waste energy preparing equally for all possible scenarios. The brain begins with expected scenarios that are continuously adjusted to match reality; the closer the match, the better we feel and the less energy we expend.
When expectations severely mismatch reality, we suffer both psychologically and physiologically, requiring more energy to realign. This explains why the second wave of COVID felt so devastating despite objectively improved circumstances-our expectations had shifted dramatically.
Serge Hollerbach, born in Leningrad in 1923, survived forced labor in Nazi factories during World War II. Despite this trauma, he maintained optimism through his love of art. At age seventy-one, he was diagnosed with macular degeneration, leaving him legally blind. Rather than despair, Hollerbach adapted his approach, emphasizing expressionism and painting from his "inner eye." He viewed his vision loss not as "a major catastrophe" but as giving him "new direction" that led him back to what he "could have been."
This "tragic optimism" works because when we expect life to be hard, we aren't surprised when it is-making life easier and improving our chances of finding meaning amid struggle. It represents non-dual thinking where life can be sad and meaningful simultaneously. When our brain's predictions align with reality, we avoid the additional suffering that comes from resistance, repression, and self-judgment.

Building a Fluid Identity: The Secret to Resilience
When Olympic speed skater Nils van der Poel shocked the sports world by publishing his training secrets after winning gold, what stood out wasn't just his workout regimen but his philosophy on identity. Unlike most Olympians who define themselves solely through their sport, van der Poel deliberately cultivated a life outside skating-drinking beers with friends on rest days and maintaining normal relationships. This fluid identity protected him from the emotional roller coaster that derails many elite athletes. "Creating meaning and value in life outside the speed skating oval helped me get through tough training periods," he explained. Paradoxically, by loosening his grip on skating as his sole identity, he became less fragile to inevitable career disruptions and ultimately performed better. "There was no longer anything to fear."
Evolution teaches us that species surviving major disruptions typically possess high complexity-the combination of differentiation (having distinct parts with various functions) and integration (those parts working cohesively together). This principle applies to individual lives facing change. Ginger Feimster exemplifies this adaptability-when her daughter Fortune came out as gay, Ginger, a devout Southern Christian who'd raised Fortune as a proper debutante, integrated seemingly contradictory identities-Christian, Southern lady, and LGBTQ advocate-under the unifying banner of being a loving mother. This complexity made her life "far more textured and meaningful" when confronted with unexpected change.
Western and Eastern cultures differ fundamentally in how they perceive identity. Westerners favor an independent self-view (seeing themselves as unique individuals influencing their environment), while Easterners embrace interdependence (viewing themselves relationally and adjusting to situations). This distinction appears in research like Imai and Gentner's study where Westerners focus on objects while Easterners prioritize context. Neither perspective is inherently superior, but understanding both allows us to adopt the most appropriate lens for different situations.
Jane Loevinger's pioneering work on ego development provides a framework for understanding how we develop fluid identities. She described the ego as an unfolding process with nine developmental stages from infancy through adulthood. As we mature, our egos ideally evolve from craving external validation to prioritizing internal meaning, eventually reaching a state of deep empathy and self-acceptance. The most advanced stage-what some call "unitive"-integrates both solidity and pliability.
When asked directly whether a self exists, the Buddha famously remained silent. Later explaining his silence, he revealed a profound truth: there are two valid perspectives on self. The "conventional self" is the distinct entity navigating daily life-the one reading these words right now. The "ultimate self" is interconnected with everything-our food, genetics, experiences, the air we breathe, and people we influence. Both selves exist simultaneously, requiring "this-and-that" rather than "this-or-that" thinking.
Chapitre 6
Core Values as Boundaries: Navigating Change with Purpose
Our identities are like rivers-constantly flowing yet contained within banks that provide direction. Without boundaries, there would be no distinct path. Georgia Durante exemplifies this concept perfectly: transitioning from model to mafia getaway driver to Hollywood stunt driver to entrepreneur, she maintained her core value of intensity while adapting to dramatically different circumstances. When the ground shifts beneath us, we need both fluidity and structure-the ability to change while maintaining a coherent sense of self.
Core values represent our fundamental beliefs and guiding principles-the attributes that matter most to us. They provide stability during change, serving as portable qualities we can express across different circumstances. In my coaching practice, I have clients identify 3-5 core values, define each with a concrete sentence, and develop specific ways to practice them daily. During uncertainty, we can ask "How might I move toward my core values?" or "How might I protect them?"
Research by Emily Falk using fMRI technology shows that reflecting on core values activates brain regions associated with viewing threats as manageable challenges rather than overwhelming obstacles. Similarly, Steven Hayes, developer of Acceptance and Commitment Therapy, explains that core values provide strength when everything feels out of control-they offer ruggedness and stability even amidst fear and chaos.
Peter Sterling's research on allostasis reveals a consistent pattern: organisms that remain healthy and resilient adapt to changing environments in ways guided by their central features and needs. Applied to human experience, our health, longevity and excellence depend on adapting in ways that protect our core values. Roger Federer exemplifies this-maintaining his love of tennis and commitment to excellence while adapting his training, technique and equipment as he aged.
The population ecology theory developed by Hannan and Freeman in the 1970s reveals three crucial principles about organizational survival: rigid structures get selected out during periods of disorder; short-term strengths often become long-term weaknesses; and major environmental changes force organizations to either transform dramatically or face extinction. The newspaper industry illustrates this perfectly-while circulation declined 60% since 1995 and revenues fell 66% since 2000, the New York Times thrived by flexibly applying its core values of independence, integrity and excellence. This combination of rugged values with flexible application enabled its growth from 1.2 million print subscribers in 2000 to over 10 million mostly digital subscribers by 2022.

From Reaction to Response: The Power of Mindful Action
The fundamental wisdom that we cannot control what happens to us but can control how we respond has endured for millennia across diverse philosophical traditions. Epictetus opened his Stoic handbook with "Of things some are in our power, and others are not," while Lao Tzu's Taoist text expressed a similar sentiment: "The master allows things to happen. She shapes them as they come." Since change itself is something we cannot control, our best approach is learning to dance with it through values-driven, effective actions.
Target fixation-becoming so focused on what's directly ahead that you crash into it-is a common phenomenon among drivers, motorcyclists, and pilots. This principle extends beyond transportation to all aspects of life: the mountain climber with summit fever who overlooks weather warnings, the parent fixated on a child's future achievements who misses present needs, or the manager so desperate for promotion they underperform on current tasks.
The martial art aikido counters this problem with zanshin, a continuing awareness that prepares you for your next action by allowing you to perceive both your immediate focus and the surrounding field simultaneously. Unlike target fixation's narrow vision, zanshin offers a flexible way of seeing that zooms in and out. As aikido master George Leonard writes, "Zanshin is the future, but zanshin is also now."
When confronted with sudden change, our amygdala activates as part of what neuroscientist Jaak Panksepp called the RAGE pathway-neural circuitry designed to help us react instantly when threatened. The SEEKING pathway, fueled by dopamine, offers an alternative that makes us feel good and motivates continued effort even along uncertain paths. According to Mark Solms' Law of Affect, our feelings predominantly direct our consciousness, causing us to repeat behaviors that make us feel good.
Cristina Martinez's story exemplifies responding rather than reacting to extreme hardship. Born in Mexico where her family made traditional barbacoa, she endured an abusive marriage that threatened her daughter Karla's future. Rather than surrendering to rage, Martinez strategically immigrated to the United States, walking fifteen days through the desert to reach Philadelphia. When her employer fired her after learning of her undocumented status, Martinez responded by noticing a gap in local cuisine and started making barbacoa from her apartment. Her cooking became so popular she eventually opened South Philly Barbacoa, which Bon Appetit named one of America's top ten new restaurants in 2016.
When facing change, we can either react with 2Ps (panic and pummel ahead) or respond with 4Ps (pause, process, plan, and proceed). Creating genuine space to process requires naming what you're feeling. UCLA researchers found that "affect labeling" significantly reduces amygdala activity while increasing prefrontal cortex engagement. The more precise your naming-"longing" instead of "sadness"-the greater your power over the emotion.
Chapitre 8
Finding Meaning Through Surrender and Connection
Sometimes change and disorder shake us to our core, and we can do everything right yet still feel depressed and void of growth. When we find ourselves in what Dante called "the dark wood," trying to force meaning can be counterproductive. In therapy, when I lamented being unable to find meaning in my suffering with OCD, my therapist offered liberating wisdom: "Not everything has to be meaningful and you don't have to grow from it. Why can't it just suck?"
Our psychological immune systems function similarly to our biological ones-they help us cope, heal and move forward after setbacks. Minor psychological injuries resolve quickly, but major ones require more time, particularly if they're unprecedented. For devastating changes like loss or identity crises, our psychological immune systems need time to organize an appropriate response. Premature attempts to generate positivity or force meaning often backfire, making us feel worse.
During my eight months in the thick of OCD, I rarely had more than two decent days in a row, and it seemed like it would last forever. Yet looking back, that period feels like a small speck of time. Research explains this perception: when we're suffering, time slows because every minute is occupied by distressing thoughts. David Eagleman's research demonstrates this phenomenon-participants who experienced the terrifying SCAD free-fall ride estimated their fall lasted 36% longer than it actually did.
Jay Ashman, a successful gym owner in Kansas City, transformed from a nationally recognized neo-Nazi leader to an anti-hate advocate. Growing up bullied for wearing hearing aids and losing his father at fifteen, Jay channeled his rage into football before joining the neo-Nazi movement at twenty-two. His turning point came when a Black man at a bar told him, "You're better than that shirt. You're better than you think you are." That night, Jay abandoned the movement. Only after nearly two decades did he find purpose in educating others about hate when he recognized familiar white supremacist rhetoric entering mainstream politics.
There is no greater source of humility than surrender. When we completely let go of control, we stop trying to fix, problem-solve, or make sense of dire circumstances. In my OCD experience, genuine progress only began when I relinquished all desire for meaning or personal growth. The part of me holding onto control was precisely what held me back.
Neuroscientist Peter Sterling identified a three-step process systems undergo when confronting significant changes: first attempting to adapt within their normal range, then "borrowing" resources, and finally expanding their capacity to accommodate a "new normal." Contrary to popular belief, resilience isn't solely an internal quality-studies show that asking for and receiving help is one of the most predictive characteristics of resilience. Like redwood trees whose roots extend outward rather than deep, intertwining with neighboring trees for support, we too need connection to withstand life's storms.

Practical Tools for Navigating Life's Changes
Research by Leidy Klotz shows that when solving problems, people overwhelmingly overlook the option to subtract elements, automatically assuming adding is the solution. This reflects our cultural bias toward having more, doing more, and being more. Jon Kabat-Zinn's concept of "voluntary simplicity" offers a counterbalance-intentionally simplifying our lives by removing physical, psychological, and social clutter.
When the world feels overwhelming, scaling back to focus only on what matters most can be profoundly helpful. Two effective approaches to voluntary simplicity are routines and rituals. Routines create predictability and automate action, requiring less mental energy to initiate. Even small accomplishments release dopamine, fueling our drive to continue. Rituals-regular, meaningful activities like weekly religious services or morning candle-lighting-provide structure during chaotic times.
There's an important distinction between "real fatigue"-when your mind-body system is genuinely depleted-and "fake fatigue"-when your system tricks you into feeling tired because you're stuck in a rut. The responses these require are opposite: real fatigue demands rest, while fake fatigue requires pushing through and taking action. Sometimes breaking out of chronic exhaustion requires combining both strategies-first genuine rest, then behavioral activation when inertia takes hold.
Like mountains that wear down and become gentler over time, our biggest challenges soften our edges and cultivate compassion. Navigating hardship requires both fierce self-discipline and fierce self-compassion-complementary approaches rather than opposing ones. Self-compassion makes us fearless by ensuring we have our own back when facing difficulties.
Research shows people who've experienced moderate adversity function better and are more satisfied with life than those who've faced either extreme hardship or very little difficulty. These individuals also cope better with future challenges, suggesting that "in moderation, whatever does not kill us may indeed make us stronger." While we shouldn't romanticize suffering-it genuinely "sucks"-it remains an unavoidable part of human experience in an impermanent world.
To integrate rugged flexibility into your life, consider these five questions: First, identify where you're pursuing fixity when change might be beneficial. Second, examine where you hold unrealistic expectations. Third, inventory your identities to see if you're over-reliant on any single one. Fourth, identify your core values to navigate challenges. Finally, recognize situations where you tend to react rather than respond.
Additional tools include switching between independent and interdependent perspectives based on the situation, responding to change with the 4Ps (Pause, Process, Plan, Proceed), leaning on routines and rituals during disorder, using behavioral activation when stuck, and giving your psychological immune system time to find meaning naturally rather than forcing it. As Mary Oliver writes, "We shake with joy, we shake with grief. What a time they have, these two, housed as they are in the same body."
