Over the years, I’ve gone from scrambling to keep my first startup afloat to settling into a life of writing and reflection. In my experience—both personal and professional—there are lessons many of us only stumble upon when we’re already knee-deep in life’s challenges.
Based on psychological insights (and a bit of real-world trial and error), here are ten key lessons we all tend to learn later than we should.
1. Time Is Your Most Precious Resource
We often treat time as if it’s endless. Yet as soon as you look back, you realize how quickly it passes.
According to psychologists, people who understand the value of time early on tend to have more satisfying careers and relationships. Cassie Mogilner Holmes, a professor at UCLA Anderson School of Management, has conducted extensive research on time and happiness. Her studies suggest that individuals who consciously manage their time in alignment with their personal values and goals tend to experience higher job satisfaction and overall well-being.
By focusing on meaningful activities and reducing time spent on less fulfilling tasks, these individuals can enhance their professional satisfaction.
I learned this lesson the hard way when I pulled countless all-nighters trying to get my first business off the ground. In hindsight, I would’ve managed my energy—and my nights—a whole lot better.
2. Emotions Are Signals, Not Inconveniences
Too many of us bottle up our feelings and ignore what they’re trying to tell us. Your emotions can be early warnings about burnout, dissatisfaction, or even an exciting opportunity you’re missing. Take them seriously.
Dr. Susan David, a psychologist at Harvard Medical School, advises individuals to view their emotions as “data, not directives,” suggesting that while emotions provide important information, they shouldn’t dictate our actions.
Similarly, author and speaker Vironika Tugaleva notes, “Emotions are not problems to be solved. They are signals to be interpreted.”
I used to brush aside my anxiety as just ‘part of the hustle,’ but looking back, those moments of stress were actually telling me to pivot or seek help.
3. Failures Aren’t Dead Ends—They’re Detours
Psychologist Carol Dweck, known for her work on the growth mindset, emphasizes that failure isn’t a reflection of ability—it’s a stepping stone to mastery.
When my second venture collapsed, it felt like the end of the road. But as Dweck’s research suggests, those who see setbacks as learning opportunities grow stronger.
That detour led me to becoming a writer at SmallBizTechnology. My failure wasn’t a dead end—it was a reroute to something even better.
4. People’s Opinions Aren’t Your Reality
As Carl Jung wisely put it, “The world will ask you who you are, and if you don’t know, the world will tell you.”
It’s tempting to let other people’s opinions shape your self-worth, but their views are colored by their own experiences and biases.
Early in my career, I made public missteps that came with criticism I wasn’t proud of. Eventually, I realized that trying to live up to others’ expectations is a sure way to lose yourself.
The only opinion that truly defines you is your own.
5. Self-Care Isn’t Selfish
Psychologist Abraham Maslow placed self-care at the foundation of his Hierarchy of Needs, recognizing that without physical and mental well-being, higher levels of achievement become difficult.
Early in my career, I saw rest as a luxury, skipping meals and ignoring exercise in pursuit of success. But as burnout hit, I learned the hard way: neglecting yourself isn’t noble—it’s unsustainable.
Prioritizing self-care isn’t selfish; it’s the foundation for long-term success.
6. Relationships Require Consistent Effort
Harvard’s Study of Adult Development—one of the longest studies on happiness—found that strong relationships are the single biggest predictor of well-being.
Yet, in the pursuit of success, I missed too many family dinners, thinking there would always be time to make it up later.
The truth? Success feels empty without people to share it with. Prioritizing relationships isn’t just good for your heart—it’s good for your health and longevity.
7. You Can’t Do Everything—And That’s Okay
Psychologist Barry Schwartz coined the term “the paradox of choice”—the more options we try to pursue, the more overwhelmed we become.
I used to say “yes” to everything, believing that every opportunity needed to be seized.
But my mentor gave me life-changing advice: “Be great at a few things instead of average at many.”
Mastery comes from focus, not frantic multitasking. Letting go of the unnecessary makes room for excellence.
8. Change Is the Only Constant
The psychological theory of resilience shows that those who adapt thrive, while those who resist change struggle.
Markets shift, industries evolve, and personal circumstances transform—so must we.
I’ve reinvented myself more times than I can count, from an eager startup founder to a writer. Each transformation felt uncertain, but each one also expanded my perspective.
As Heraclitus said, “No man ever steps in the same river twice.” The sooner you embrace change, the better you’ll navigate it.
9. Gratitude Shifts Your Perspective
Dr. Martin Seligman, the founder of positive psychology, discovered that practicing gratitude rewires the brain for greater happiness and resilience.
Instead of focusing on what’s missing, acknowledging what we already have creates a powerful shift.
Even on my hardest days, I remind myself: I have supportive readers, a fulfilling job, and the chance to share what I’ve learned.
Gratitude doesn’t erase struggles, but it transforms how we experience them.
10. It’s Never Too Late for a Fresh Start
Psychologist Erik Erikson’s theory of lifespan development reminds us that personal growth isn’t confined to youth—every stage of life presents opportunities for reinvention.
Society loves to tell us we’re ‘too old’ or ‘too far gone’ to change. That’s nonsense. I pivoted careers after years in entrepreneurship, and it was one of the best decisions I’ve ever made.
As Viktor Frankl said, “When we are no longer able to change a situation, we are challenged to change ourselves.”
It’s never too late to begin again—just make sure you’re the one writing your next chapter.
Parting Thoughts
Life doesn’t come with a manual, but psychology and shared experiences can offer a roadmap. Some of these lessons might seem obvious—but in practice, we often overlook them until we’re forced to learn the hard way. If you take these insights to heart now, you’ll be miles ahead of where I was at your stage.
Remember, nobody has life completely figured out, but each day is an opportunity to get a little closer. So, take it from a guy who’s made more than a few mistakes: don’t wait until it’s ‘too late’ to live wisely and well.
