It’s estimated that the average person will spend 90,000 hours of their life working—that’s roughly a thousand weeks, or a third of our lives.
Over the years, I’ve watched many of my Oxford and Harvard university classmates come to reunions and alumni dinners disillusioned, burned out, unhappy, divorced or separated, and alienated from themselves and their friends and families. I can guarantee you that not a single one of them graduated with the deliberate strategy of getting to this stage of their careers unfulfilled. Yet a shocking number of them unwittingly implemented that strategy. They seemed successful—the boats, the bank accounts, the fancy titles—but these people never knew and still do not know how they wanted to spend their time, talents and energy.
Career success is first and foremost a matter of perspective, and being happy with what you have achieved is a choice. But there are five common drivers that everyone can measure theirs by—meaningful metrics to help understand what we want and recognize success when we get it.
1. Treat your career like a journey, not a destination
Many ambitious people fall into what psychologists call Deferred Happiness Syndrome—the belief that “once I get X, then life will begin. Once I get the degree, the promotion, buy the house, or pay this off, then I can finally be happy.” The problem is that the X keeps moving further away.
Achievements, although impressive, become mere preludes to some idyllic future that never fully arrives. In the process, people often neglect relationships, hobbies, and personal well-being, believing they can make up for it later. They miss opportunities for fulfilment that exist in the present moment because their focus remains fixed on what still needs to be achieved. Sustainable career happiness comes from appreciating the path while you are on it, not postponing fulfilment until some imagined future version of success. No number of boats will make up for the emptiness of arriving at 90,000 hours having not enjoyed the 89,999 that came before.
2. Don’t chase extrinsic motivation—you might find you’re living someone else’s dream
Many people spend years chasing extrinsic measures of success (money, status, titles, prestige or approval from others) believing those things will eventually make them feel fulfilled. Often, they do achieve them. But the satisfaction is surprisingly short lived because the success was externally defined, not internally chosen. Understanding your intrinsic motivation and making sure you are not living someone else’s dream is a key driver of achieving happiness in your career.
One executive I coached had the penthouse apartment, luxury cars, elite career, and social status that many people aspire to, yet she realized she had spent her life living other people’s expectations: first her parents’, then her peers’, then her partner’s and children’s. The applause felt like progress, but it was not purposeful because it was never truly her dream.
Real career happiness comes from understanding your intrinsic motivations—mastery, creativity, contribution, meaning, connection, or compassion—and building a life aligned with those values. Chasing purely extrinsic success can leave you accomplished on paper but deeply unfulfilled underneath it all.
3. Be careful of what you say no to
Building a successful career requires focus, sacrifice, and trade-offs. Inevitably, you cannot say yes to everything, but you should be careful about what you say no to. Many highly successful people wake up later realizing they repeatedly said no to the things that mattered most: relationships, health, family moments, creativity, or experiences that gave life meaning. There are an awful lot of very successful, very unhappy people because they spent years postponing happiness in pursuit of the next achievement (see Deferred Happiness Syndrome above!).
One useful practice is Episodic Future Thinking: imagining how your future self will feel about today’s decisions. Will joining one more meeting at 5:04 p.m. matter more than attending your daughter’s soccer tournament or your son’s concert? Research suggests that around 90% of the time you will ever spend with your children happens before they turn 18. Career success is important, but the key is making sure you are not unintentionally saying no to the people and moments that matter far more.
4. Are you bringing people with you?
Career happiness is shaped not only by what you achieve, but by who you share the journey with. One of the hidden costs of success without fulfillment is loneliness. Many high-achieving people spend years climbing the ladder, only to discover they feel isolated at the top. In the pursuit of performance and progress, relationships are often unintentionally deprioritized. The result is a hollow kind of success—one with few people to celebrate with and little sense of connection to what’s been achieved. Some high achievers realize too late that they never stopped to build deep relationships along the way; others find they no longer know how to connect beyond work. It’s one of the most common regrets in successful careers: reaching the top and realizing you didn’t bring anyone with you. Real success is rarely built alone and it’s never fully enjoyed in isolation.
5. Take time to reflect and experience gratitude and appreciation
Many high achievers feel unsettled when they look back on their careers because they didn’t take time to feel or express gratitude for their achievements or appreciate their journey.
In Japanese culture, this is captured by the idea of kansha—a deep, mindful gratitude that includes both positive and challenging experiences. It reflects a way of seeing life that values the whole journey, not just the outcomes. This connects with mottainai, the idea of not wasting or taking for granted what you have, and ikigai, the importance of meaning and purpose in life and experience.
Together, these ideas highlight an important reflection point: whether your success feels “whole,” or whether it is narrowly focused on achievement alone. Real gratitude is not only about recognizing what you have become but also sharing that appreciation with others. Without both, many people find their success feels strangely empty, even when everything looks right on the outside.
You’ll notice that many of the integral pillars of career happiness above stem from the life we lead outside of work, as paradoxical as it sounds. Remember that for the 90,000 hours of life we spend at work, we have another two thirds to spend wisely too. Prioritizing our own sense of work-life balance and fulfillment—driven by intrinsic motivation—helps us all become happier. And wouldn’t that be something to look forward to.
