The Ancient Philosophy That Transformed an Olympic Champion
When Mark Tuitert faced his potentially only shot at Olympic glory in 2010 after missing two previous Games, he was consumed by questions: What if he failed? What if twelve years of training were for nothing? It was during these tense weeks that he first encountered Stoic philosophy-an ancient wisdom tradition that would transform not just his athletic career but his entire approach to life. The philosophy that helped Roman emperors and slaves alike navigate life's challenges provided Tuitert with a framework to channel his drive while becoming calmer and more effective. Today, Stoicism has experienced a remarkable renaissance, embraced by NFL coaches, Silicon Valley executives, and celebrities like Tim Ferriss who credit it with helping them achieve success under pressure. Through Tuitert's journey from Olympic disappointment to gold medal triumph, we discover how these ancient principles offer timeless wisdom for modern challenges.

Transforming Setbacks into Stepping Stones
As a twenty-one-year-old speed skater in 2001, my life revolved around conquering the world. Working toward the next year's Olympics, I mentally wrote my future triumphs on the calendar-failure wasn't in my vocabulary. As the Netherlands' most promising young speed skater, I negotiated ambitious contracts with sponsors captivated by my confidence.
To deliver on these promises, I eliminated all rest days from my training schedule. I consistently exceeded requirements-skating eleven laps when asked for ten, extending training camps, and turning two-hour bike rides into three-hour sessions. My philosophy was simple: working harder means skating faster.
But I was overdoing it. My body broke down-I got sick at strange times, and whenever I recovered, I pushed even harder to make up for lost time, creating a vicious cycle. Three months before the Salt Lake City Olympics, I was seriously overtrained-the equivalent of burnout. While the Netherlands won eight medals, I watched from my couch, barely able to turn on the TV. The commentators declared it was the end for Tuitert.
Interestingly, Stoicism itself emerged from adversity. The philosophy's founder, Zeno of Citium, was a wealthy merchant who lost everything in a shipwreck near Athens around 300 BC. Finding himself at the Agora, Athens' marketplace and intellectual center, he turned this catastrophe into opportunity, studying under philosophers before establishing his own school. "Now that I've suffered shipwreck," he declared, "I'm on a good journey."
Stoic philosophy emerged during times of war, famine, and epidemics-when physical and mental fortitude were essential. Today in the West, we face different challenges-excess rather than scarcity. We rediscover ancient practices like fasting or cold water immersion not just for physical benefits but to train ourselves against hardship.
The Stoic approach involves mentally rehearsing what frightens you. What if you lost your job tomorrow? What if your presentation fails? By contemplating these possibilities in advance, you're not shaken when they actually occur. Life rarely follows a predictable path-relationships end, jobs disappear, pandemics strike. A Stoic enjoys dreams of success while detaching from the negative emotions that arise when dreams don't materialize.
While my teammates shined at the Olympics and others speculated about my career's end, I immersed myself in books about training theory, psychology, and philosophy. I discovered I wasn't alone in my mistakes-many people in all fields wear blinders until they hit walls. Reading about athletes and entrepreneurs who overcame deep lows gave me hope.
Eventually I recovered, though humbled. Understanding what happened prevented me from repeating my mistakes. The setback taught me to visualize potential failures in detail, finding calm and strength that prevents me from being shaken regardless of circumstances. I learned that setbacks aren't stop signs but signposts-necessary risks on the path to raising the bar and chasing dreams.
Capítulo 3
The Art of Understanding Over Judgment
As a child, I never expected my parents to divorce-parents understand the world and know what they're doing, right? Yet around 1999, just as my speed skating career was breaking through, it happened. Their emotions created a chaotic mix of sadness, love, incomprehension and pain. I particularly clashed with my father, whose anger I couldn't understand and even resented.
I sided completely with my mother, helping her buy a house and offering support. With my father, I chose distance rather than understanding, breaking all contact. Despite people reminding me "He's still your dad," I remained firm in my judgment: he was wrong, the villain, creating only negative energy. It felt like the only way to avoid being overwhelmed by out-of-control emotions.
Contrary to popular belief, Stoics don't ignore emotions-they understand them. Emotions reflect our judgments about events, neither inherently good nor bad. Stoics examine the thinking behind emotions rather than acting on immediate reactions like frustration or rage. They treat emotional wounds like physical ones, seeking to expose and heal underlying judgments.
While first impressions (like fear during a storm) are involuntary, a Stoic chooses not to be controlled by them, staying calm to act judiciously. By questioning our emotional reactions-"Why am I jealous? What judgment underlies this?"-we free ourselves from negative thinking, gain perspective, and make better decisions.
Athletes perform best when immersed in the physical moment rather than worrying about outcomes beyond their control. Allowing yourself to be provoked or distracted leads to lost concentration, diminished enjoyment, and poorer results. The key is maintaining focus on the task and physical experience that brings fulfillment.
Five years after breaking contact with my father, I realized my skating challenges stemmed from personal judgments, not technical issues. Despite having an excellent team, something was missing. I finally called my father, fearing his reaction but knowing nothing would change without action. His response wasn't angry but happy-time had healed some wounds.
My freedom came from examining my judgment about what fatherhood meant and recognizing my dad's powerlessness. By releasing this judgment, I gained energy and peace. Four years later at the Vancouver Olympics, my father was there cheering me on, a weight lifted from both our shoulders.
Capítulo 4
The Paradox of Achievement: Focus on Process, Not Outcome
Professional sports offers more disappointment than success-only one person can win. After missing Olympic opportunities twice, I finally got my chance at twenty-nine in Vancouver. Walking into the stadium filled with Dutch supporters and cameras, I felt the pressure of twelve years of training for less than two minutes of performance.
The deeply cherished desire for gold can transform into fear as you contemplate everything that might go wrong-your opponent, ice conditions, the starter's timing. In the weeks before my race, I questioned whether all the sacrifice would be worth it if I failed.
The fundamental Stoic principle is dividing life into what you can and cannot control. Epictetus, born into slavery, embodied this wisdom-maintaining composure even when his master broke his leg. By controlling his reaction rather than protesting uselessly, he maintained power over himself. As a teacher, he would call his followers "slaves" when they let themselves be carried away by circumstances.
Wealth, health, and victory are ultimately outside our control. We can do our best, but results aren't up to us-only our efforts are. Like an archer who focuses on perfect technique rather than hitting the target, true peace comes from execution, not outcome.
Entrepreneurship is similarly intense-every decision begins and ends with you. When my chewing gum company's packaging factory burned down during riots in 2020, our revenue stream instantly dried up. Rather than despair, I focused on what I could control: launching our new website and laying the foundation for this book. Focusing on actionable possibilities rather than circumstances beyond your control creates energy and forward momentum.
At the Olympics, I applied Stoic principles in the crucial moment. As I stepped onto the ice amid the packed stands, I focused only on what I could control-not my competitors, not the ice conditions, not even winning gold. I shrunk my world to just the first few strides after the starting gun.
By intentionally letting go of outcomes and focusing on perfect execution, I found calm precision. One minute, forty-five seconds, and fifty-seven milliseconds later, I won gold. Not by obsessing over victory, but by focusing entirely on what I could control.
Capítulo 5
The Individual Within the Collective
At the beginning of my speed skating career, I trained as an all-rounder with both sprinters and distance skaters, including accomplished athletes like Gianni Romme and Erben Wennemars. We were simultaneously teammates and competitors for the same medals. Speed skaters skate in single-file to block the wind for each other, helping everyone reach higher levels.
But when individual egos outweigh team interests, cooperation breaks down-sprinters might skate too fast for others to follow, or distance skaters might set a brutal pace that drops everyone else. While this might stroke individual egos, overall performance suffers and enjoyment vanishes.
Though Stoicism focuses on personal development, having good relationships with others is equally important. Self-preservation is our first natural impulse, but for social creatures like humans, doing good by others is also a survival strategy. In the Stoic sense, you can't do anything good for yourself at another's expense. Seneca believed it our duty to mean something to others-preferably many, but if not possible, then to a small group, to those close to you, or at minimum, to yourself.
Children excel at finding weak spots in parents and siblings. While Seneca's advice to "count to ten" is easier said than done, my wife and I try to teach our children Stoic self-reflection. When our daughter says, "My little brother is stupid," we explain that what she really means is "I think my little brother is behaving stupidly"-distinguishing between disliking someone's behavior rather than the person themselves.
In the eastern Netherlands where I grew up, we practice noaberschap (neighborliness)-an unwritten rule that neighbors must help one another. If a farmer falls ill, neighbors take over their work, forming a mutual support system that originated as health insurance in remote areas. This community spirit represents the foundation of social democracy: helping those in need becomes the glue binding us together. Self-preservation and community spirit aren't contradictory-they're complementary.
Capítulo 6
Embracing What Cannot Be Changed
Nobody wants to get sick, especially athletes for whom even a slight cold disrupts training. As European all-round champion and world-record holder, I once ignored a sore throat to complete crucial interval training, turning a mild cold into flu. The Stoics teach that we're better off humbly accepting nature rather than fighting it-like a dog tied to a cart who can either run along happily or resist and suffer.
The Stoics compare our life course to a dog tied to a cart rolling downhill. We can either run alongside and enjoy the ride or resist futilely and turn the journey into torture. Epictetus teaches us not only to accept every situation but to love it, calling it foolish to wish things were different-like "wishing for figs in winter." Similarly, Nietzsche's amor fati (love your fate) suggests the key to happiness is embracing rather than resisting reality.
Dutch snowboarder Bibian Mentel exemplifies Stoic resilience. Just as she reached world-class status, she faced leg amputation due to cancer. Rather than despairing, she immediately asked her surgeon about prosthetic options. Four months later, she returned to snowboarding, eventually winning three Paralympic gold medals and promoting snowboarding as a Paralympic sport. Even facing death, she embodied Marcus Aurelius's wisdom that what's humanly possible is attainable with the right mindset.
True friendship isn't about giving unsolicited advice but offering support and asking good questions. The Socratic dialogue technique-omitting your own opinions and asking factual questions based on the other's answers-creates deeper conversations. When a friend shared his dilemma about balancing success with inner calm, I resisted judging his surprising answer ("success is when others find me successful") and instead asked questions that led to meaningful exchange.
My coach Wim den Elsen taught me to "see sick days as natural rest days." Rather than fighting illness, which is counterproductive, we should accept it as part of life's natural course. During my overtraining period in 2002, I learned guitar-an activity that engaged my brain differently while providing mental distraction from frustration.
Accepting situations that block our path doesn't come naturally, especially for competitors, but fighting against reality often causes more harm than good. We can only find peace after realizing that fighting against fate is actually fighting against ourselves. What we can't change, we must accept-and ultimately love our fortune, difficult though that may be.
Capítulo 7
Mortality as Life's Greatest Motivator
When my mother took her own life after years of depression, I was devastated but not surprised. Though I struggled with feelings of incomprehension and anger at what seemed like giving up, I've come to understand that death is central to Stoic philosophy. The Stoics viewed death without fear-Seneca wrote that dying is an everyday process as each passing day brings us closer to our end. Many Stoic philosophers faced death with remarkable composure, even disdain. Their attitude wasn't morbid but life-affirming: understanding our mortality motivates us to live well and avoid deathbed regrets.
Death occupies a central place in Stoic philosophy. Seneca, advisor to Emperor Nero, wrote extensively about it, reflecting on life's uncertainty. He viewed dying as a daily process-with each day, another part of us is taken. When ordered to take his own life, Seneca faced death with composure.
Most Stoics didn't believe in an afterlife, instead using death's inevitability as a remedy against arrogance and a motivation to live well. As Epictetus said: "I have to die. If it is now, then I die now; if later, then now I will take my lunch." For Stoics, dying well meant looking back without regret-the ultimate test of whether one had truly lived well.
Though it seems absurd that everything we cherish will someday vanish, this understanding can be valuable rather than depressing. It motivates us to spend our time well. The top regret of dying people, according to caregiver Bronnie Ware, is not living true to oneself but living as others expected.
Death awareness gives us a crucial daily choice: are we spending time on what we truly value, or letting ourselves be carried away by choices we'll regret? Why cling to being right in arguments when letting go brings peace? Why not take time for nature instead of being consumed by busyness? Understanding our finite time helps us avoid being led by daily issues and impulses.
My mother's depression prevented her from living fully-she had been dying for ten years before her actual death. One of my hardest choices was telling her to stay home during the Vancouver Games, as her condition would make the trip too difficult for everyone.
Two weeks after her passing, I found myself skating on natural ice in the Weerribben where I first learned as a boy. Despite being left out of tournament selections and struggling to find sponsors during an economic crisis, I knew I'd regret not seizing this rare opportunity. Gliding across the frozen waters under the rising sun, I felt alive despite my grief. With death in mind, it becomes easier to define what truly matters.
Instead of adding more items to our yearly resolutions, a Stoic approach asks what we want to do less of. By cutting things out first, we can focus more time and energy on what truly matters. This is particularly challenging for those who get excited by big ideas and pick things up quickly. Making a list of things to stop doing or outsource can create space for what's truly important.
Capítulo 8
The True Nature of Happiness
As athletes and entrepreneurs, we constantly chase the next achievement, believing happiness lies at the finish line. Yet the euphoria of success-even Olympic gold-lasts merely three months before we return to our baseline happiness and seek the next high. The Stoics understood that true happiness isn't found in external achievements but in the process itself-eudaimonia, a state of inner calm and self-development regardless of circumstances.
The Stoics observed that even the most outwardly successful people-emperors, wealthy businessmen, athletes-often felt miserable. They strove instead for eudaimonia: growth and flourishing by overcoming challenges while maintaining inner calm under all conditions. This happiness isn't measured by pleasure or the absence of pain, but by developing oneself and finding meaning through struggle. As Seneca demonstrated, even wealth is acceptable if you can genuinely detach yourself from possessions rather than being ruled by fear of losing them.
After winning Olympic gold, I expected sponsorship deals and flashy commercials, but the economic crisis meant settling for a Kinder Bueno ad where someone asks, "Aren't you Mark Tuitert, that speed skater?" Years later, struggling before Olympic qualifiers, my coach Gerard van Velde helped me realize I was attaching too much to my champion label.
By embracing that I had nothing to lose-appreciating my journey rather than fixating on results-I found the calm that helped me qualify for Sochi. True happiness came not from medals but from rising to challenges, growing, and finding inner peace along the way.
Whether you're a CEO, athlete, or performer, being in the spotlight creates immense pressure. Even champions like Usain Bolt feel this pressure but have learned to manage it. My technique before important races was cracking jokes with physical therapists to momentarily shift my thoughts away from the pressure, controlling my emotions rather than letting them control me.
The best way to become happier is to increase your gratitude, focusing on what you have rather than what you lack. Keep a notebook by your bed and before turning off the light, write down three things you're thankful for today-from significant blessings like your partner's love to small comforts like a comfortable pillow.
Capítulo 9
Finding Direction in a World of Possibilities
After retiring from professional skating, I lost my North Star-the clear Olympic goal that had structured my entire life. Without direction, I wandered aimlessly, meeting with anyone who might guide me. When a friend advised me to "get out and work," I was initially indignant-hadn't I trained twice daily for fifteen years? But in job interviews, I struggled to identify my strengths beyond "skating laps counterclockwise." As Seneca observed, without knowing which port we're sailing to, no wind is favorable.
Seneca marveled at people drifting through life without direction while complaining nothing worked out for them. The Stoic approach is to think carefully about what you want but also take action - contemplation and action must exist together. Like navigating with Google Maps, you only know if you're heading the right way once you start walking.
Life's journey never follows a straight line but involves constant course corrections. For Stoics, the sailing itself matters more than reaching harbor. Rather than following others' well-worn paths, we must find routes aligned with our nature. Having a compass (direction) is better than a map (perfect route). Marcus Aurelius exemplified this by applying his philosophical nature to his unexpected role as emperor, fulfilling his potential despite it not being his original path.
Young people often set abstract, distant goals like "saving the world" but struggle with motivation when progress seems minimal. Instead of fixating on grand purposes, discover your direction first. True fulfillment comes from daily work that aligns with your nature - problems you genuinely want to tackle regardless of payment.
By trying different paths, you learn what doesn't suit you through action, not just contemplation. The Life Direction Triangle model helps identify your natural coordinates - like the author's triangle of autonomy, sports, and philosophy - creating a personal compass where these elements reinforce each other while honoring your essential nature.
Studying isn't a competition to demonstrate brilliance but a pathway to expand your life toolbox. When you find fulfillment in learning itself, you develop a lifelong growth mindset. A Stoic never assumes they're the wisest but continues searching, embodying the eternal student. This philosophy inspired me to launch the podcast "Drive," interviewing accomplished individuals across various fields to learn better questioning techniques and understand different motivations.
Capítulo 10
Character as Life's Ultimate Project
The Stoics considered character development their most crucial undertaking. Marcus Aurelius advised preparing daily to face "interference, ingratitude, insolence, disloyalty, ill-will, and selfishness" by recognizing these stem from others' inability to distinguish good from evil.
The Stoics used the concept of the sage - someone living in perfect harmony with nature according to the highest human values - as their aspirational model. The sage embodies the four cardinal virtues: courage, temperance, justice, and wisdom. These "cardinal" virtues (from Latin "cardo" meaning "hinge") are the pivot points around which life turns.
These aren't simply values like cleanliness or honesty, but character traits anyone can develop to lead a good life through right action for oneself and others. Though the sage remains an unattainable ideal for virtually everyone, we should still strive toward it as our guiding example.
I share with my son Tom videos of the All Blacks rugby team, not just for their impressive haka war dance, but for their core values: "Better people make better All Blacks." This philosophy extends beyond sports to all aspects of life. The All Blacks demonstrate that winning doesn't require being disrespectful-it requires courage to enter competition, temperance to stay calm under pressure, justice to respect rules and calls, and wisdom to know when to give your all versus when to let others shine. These cardinal virtues form the foundation of good character in any endeavor.
Stoic leaders make decisions based on guiding principles and values they want to instill in those they lead. Marcus Aurelius exemplifies this-despite being perhaps the most powerful man on earth as Roman emperor, his first act was seeking rapprochement with the senate, demonstrating his principle that he served society. Stoic leaders don't pursue popularity; they become respected by doing what's right. They maintain composure under pressure while considering others' needs.
Epictetus used Olympic athletes as examples of commitment-wanting something requires understanding and accepting what it truly entails. The Stoics weren't concerned with winning arguments or abstract theories, but with practical application in daily life. Marcus Aurelius didn't write philosophical treatises but practical notes to guide his daily decisions as emperor. Philosophy for Stoics isn't theoretical but a living way of thinking applied through action. Our actions, not our words, demonstrate whether we've truly absorbed these lessons.
Ideas may seem promising on paper, but only real-world execution reveals their true value. As an entrepreneur, I learned that regardless of business plans and presentations, success depends on market factors beyond my control. We often delude ourselves about our capabilities until failure teaches us otherwise. Failure isn't pointless-it confronts us with essential questions about our true desires and tests our convictions. The Stoic mindset helps us approach these situations with resilience and learn from them.
I once tried to compete in marathon skating with minimal training while juggling other commitments, only to face inevitable failure. This experience taught me that you can't claim to want something while refusing to take necessary actions to achieve it. This realization eventually led me to quit my job to pursue entrepreneurship, understanding it would require investment, perseverance, courage and collaboration-the ultimate test of my ideas.
My journey to Olympic gold came at 29 rather than the early success I expected at 21. I advise young professionals who haven't found their calling or achieved expected success to recognize time as their ally. This doesn't mean postponing action-rather, take action now but measure results over the long term. Short-term action leads to long-term results. You can't say you want something without taking necessary action - that's self-deception. Whether pursuing Olympic gold or entrepreneurship, you must fully commit daily to what you want. Finding your drive involves emotional trial and error because you're fully investing yourself with "skin in the game." Even with doubts, remind yourself that achievement takes time, patience and perseverance.
