Escape the Hedonic Treadmill in Your 20s
- The hedonic treadmill describes how people quickly adapt to new possessions and achievements, making them feel unsatisfying after the initial excitement wears off. Social media amplifies this problem by showing everyone's highlight reels, making your regular life seem inadequate in comparison.
- Instagram and social platforms have made the treadmill worse because people share only the best 0.1% of their lives, creating unrealistic expectations about what normal life should look like. "Everyone is living a more awesome life than me like every day, every day all the time my life sucks," reflects this distorted perception.
- The key insight is that there are only so many good things and toys in life, and people who grow up super rich often struggle with having experienced everything too early. This creates a dangerous pattern where you exhaust life's pleasures before you've had time to truly appreciate them.
- You can hack the hedonic treadmill by intentionally delaying each step and giving yourself room for upside. Your first apartment after college shouldn't be much nicer than your dorm room, even if you can afford better, because this preserves your ability to appreciate upgrades later.
However, this approach requires discipline in a culture that encourages immediate gratification. The trade-off is worth it because it allows you to focus on more meaningful pursuits during your most flexible decade.
Don't Speedrun Life's Major Experiences
- Your first place after college should not be much nicer than your dorm room, even if you landed a job at Facebook and can afford luxury. This principle applies across multiple areas: your first vacations shouldn't be extravagant, and your first car doesn't need to be impressive.
- The reasoning behind this delayed gratification strategy is mathematical - you're leaving yourself significantly more upside for future appreciation. When you start modestly, every upgrade feels meaningful and satisfying rather than just meeting an elevated baseline expectation.
- This approach helps remove hedonic distractions from your 20s, allowing you to focus on more important developmental activities. Instead of chasing lifestyle upgrades, you can invest energy in skills, relationships, and experiences that compound over time.
- The alternative path leads to a common trap where people exhaust their capacity for appreciation early. "There's only so many good things there's only so many toys" - and if you consume them all immediately, you'll find yourself bored and unsatisfied despite material success.
Many people resist this advice because it feels like artificial deprivation, but the psychological benefits of having something to look forward to outweigh the temporary sacrifice of living below your means.
Go Hardcore Early in Your Career
- The best strategy is to "do the most hardcore thing early in your career because you can always mellow out, you can always pull the ripcord and do less hard things." Going the other direction is much more difficult - transitioning from mellow to ambitious becomes increasingly challenging with age.
- This principle applies across different career paths, not just startups. If you choose medical school, that's hardcore, but once you have your MD, "you could be a more mellow doctor, you don't have to be crazy, or you could be like a part time plastic surgeon." The same logic applies to law school, investment banking, or even creative fields like writing.
- Many people receive conflicting messages about work-life balance and burnout risk, which creates confusion about whether intense effort is worthwhile. However, being young is actually when you have the highest capacity for hard work and recovery from setbacks.
- The hardcore approach early on provides more options later in life. Whether you want to be a novelist, consultant, or entrepreneur, "the more hardcore path just gives you more options when you're older" because you've already proven your capabilities and built valuable skills.
The key insight is that you don't really know your capacity until you test it, and your 20s are the optimal time for this experimentation when the downside risks are minimal.
Embrace Strategic Risk-Taking
- Your 20s represent a unique window for risk-taking because you typically don't have kids, a mortgage, elderly parents, or other major responsibilities that make you naturally risk-averse. "Most people in their 20s don't have any of those things to worry about" yet many still avoid taking career risks.
- Many young people are discouraged from taking risks by well-meaning parents who view things like starting a company as potentially life-destroying. However, this fear is often based on outdated assumptions about job security that no longer apply in today's economy.
- The traditional path of getting a stable job at a large company for life has already been disproven. "The idea that you get a job and you can do that job at that company for the rest of your life has already been disproven" - so the supposed safety of conventional careers is largely illusory.
- A useful exercise for evaluating risk is to explicitly walk through worst-case scenarios. "What's the worst that can happen yeah and you just okay be explicit this happens okay well if that happens then what can you do could you go get a job they're like yes" - often the downside isn't as catastrophic as feared.
The caveat is that this advice assumes your starting conditions allow for risk-taking. If you have genuine financial obligations or constraints, the calculation changes, but many people who could take risks don't realize their flexibility.
Navigate Family Expectations Thoughtfully
- Parents naturally want to have a vision for their children's lives, and "it's hard to not want to have a vision for your kids yeah it's hard to not have expectations it's hard to not have dreams." This creates tension when your goals diverge from their plans.
- Your 20s represent the first time when your life plan becomes truly your own. "When you're 23 and you're following your like that's your are you living your own life for the expectations of you" - you're now choosing to follow someone else's blueprint rather than being required to do so.
- The danger lies in never questioning inherited plans and assumptions. Many people "look back and they're like oh I didn't question my plan enough in my 20s yeah like I woke up in my 30s and was like wait did I really like the path that I walk did I ever spend a lot of time thinking about what I want."
- By your 30s, some life choices become more difficult to reverse because you've built commitments and responsibilities around them. The window for major life pivots narrows significantly as you accumulate obligations and dependencies.
This doesn't mean rejecting your parents' advice entirely - their plan might be excellent. The key is making a conscious choice about your direction rather than defaulting to expectations without examination.
Choose Your Peer Group Strategically
- Your personality is fundamentally shaped by your social environment. "Your personality is just an amalgam of whatever the six or seven people you spend the most time with yeah and a lot of the things that we think are our own ideas is or our own identity is no it's not it's just your like this is you just soaked it up from your peer group."
- The influence of random assignments like college roommates can have enormous impacts on your life trajectory. "Think about how much of our lives are dictated by who we get randomly assigned as roommates in college, like is there any bigger decision in what yeah what kind of person you grow up to be is like random roommate assignments like freshman year."
- This social influence is hackable - you can deliberately choose to spend time with different people based on who you want to become more like. If you want to start a business, surrounding yourself with entrepreneurial friends makes a massive difference in how normal and achievable that goal seems.
- Everyone becomes a centrist relative to their peer group. "Everyone becomes a Centrist in whoever they're surrounded by and so if you're surrounded by extremists on any topic you'll think you're a Centrist but you're actually an extremist" - your reference point shapes your sense of what's normal or extreme.
- Changing your peer group might require changing where you work, live, or spend time. "Changing those people might require changing where you work, changing where you live um moving to a different city" - and your 20s are the ideal time for these major transitions.
Your strongest friendships will survive geographical and lifestyle changes, so you're not risking as much as you might think by making strategic moves to upgrade your social environment.
Build Stable Long-Term Relationships
- Contrary to popular advice about avoiding commitment in your 20s, seeking stable long-term relationships can actually enhance your ability to pursue ambitious goals. Having "a really good partner actually unlocks some of the gears" when you're working at maximum effort on challenging projects.
- A strong romantic partnership provides crucial emotional recharge between intense work sessions. "Having someone to come home to that you really enjoy being around kind of recharges you faster" - this support system becomes especially valuable during stressful periods of career building.
- Developing relationship skills in your 20s is practice for your future self. "Being in the practice of being in stable relationships is good like it is a good hobby to develop that your future self will enjoy" - these interpersonal capabilities compound over time.
- The opposite pattern can create debt for your future self. Someone who "never wants stable relationships that just wants to be on Tinder that doesn't ever want to be tied down" is training themselves in habits that make it harder to form lasting partnerships later.
This advice doesn't mean rushing into marriage or having kids early - it means developing the capacity for deep, committed relationships while you're still figuring out other aspects of your life.
Get Around Talented People Regardless of Background
- Don't let educational pedigree limit your ambitions. The key is to "identify what companies or workplaces have the most interesting people doing the work you're most interested in" and find ways to get any job there, regardless of how prestigious the role initially appears.
- Once you're in an organization with talented people, "you will get to meet and be around all these other people and soak up the culture" - proximity to excellence is more valuable than the specific job title or initial compensation.
- Many successful people in Silicon Valley "didn't go to a good school yeah that just got in the door somewhere yes with any kind of random job yes and once they were in there their intellect and their skills and their abilities allowed them to win people over."
- Super talented people often work at smaller, earlier-stage companies where getting hired is easier than at large corporations. "Many times super talented people are at the beginning of stuff, yeah where getting in is easier" - though these roles come with more risk and uncertainty.
- A compelling example: an intern who started as a security guard at a housing development leveraged that experience into a content moderation role, eventually founding a company generating tens of millions in revenue. His qualification was simply "I work basically the gate and it's like a college kind of housing community and nights and weekends are just crazy."
The key insight is that getting "in the game" matters more than your starting position - small companies read every email and are often desperate enough to give unconventional candidates opportunities.
