Honestly, looking back at my twenty-something self feels like watching a grainy home movie of a stranger who thought they had the world figured out because they read a few productivity blogs. We spend so much of our early adulthood chasing these specific milestones—the degree, the "adult" job, the curated apartment—thinking that once we hit them, a switch flips. We assume the uncertainty just evaporates. But lately, I’ve been sitting with a recurring thought: I wish I knew that the real work doesn't even start until you’ve checked all those boxes and realized you're still the same messy person, just with higher stakes and slower metabolism.
It’s a weird realization. You spend years sprinting toward a finish line that doesn't actually exist. Then you hit thirty, or thirty-five, and the "instruction manual" everyone seemed to be following suddenly runs out of pages. You're left standing there, holding a mortgage or a career path or a long-term relationship, wondering why nobody told you that the maintenance of a life is significantly harder than the building of it.
The Financial Reality I Wish I Knew Earlier
Most financial advice is frankly boring. It’s all "stop buying lattes" and "max out your 401k." While that’s fine for a spreadsheet, it ignores the psychological weight of money. I wish I knew that financial freedom isn't about the number in your bank account as much as it is about the "burn rate" of your anxiety. You can earn six figures and still feel poor if your lifestyle scales up exactly alongside your salary. It’s called lifestyle creep, and it’s a predatory beast.
I remember talking to a friend who works in high-end wealth management in New York. He told me about clients making $500,000 a year who were genuinely stressed about their monthly bills. That blew my mind. But it’s real. You get the nicer car, the better gym membership, the organic grocery delivery, and suddenly, you’re trapped. You can’t quit the job you hate because your life costs too much to maintain. I wish I’d understood that keeping your overhead low is the ultimate power move. It’s the only thing that gives you the "walk-away power" to tell a toxic boss to shove it.
Also, taxes. Why does no one talk about how complicated they get once you stop being a standard W-2 employee? If you start a side hustle or go freelance, the government doesn't just take a cut; they expect you to be a psychic and predict exactly how much you'll owe months in advance. It’s a steep learning curve that usually involves at least one panicked phone call to an accountant in mid-April.
Health Isn't a Given (And It Breaks Fast)
In your twenties, your body is basically a rental car that you can beat up without consequence. You can survive on four hours of sleep and cold pizza. Then, seemingly overnight, you wake up with "sleep injuries." You literally slept wrong, and now your neck doesn't turn left for three days. It’s absurd.

The thing I wish I knew about health is that it’s cumulative. You aren't "healthy" just because you aren't currently sick. You’re either building a reserve or depleting one. I’ve started following the work of Dr. Peter Attia, who talks a lot about the "Marginal Decade"—the last ten years of your life. He argues that if you want to be able to pick up your grandkids or hike when you're 80, you have to be doing the heavy lifting now. You can't start training for old age when you're already old.
It’s not just about the gym, though. It’s the boring stuff. Fiber. Stretching. Dental flossing. Seriously, go floss. Gum disease is linked to heart health in ways that are actually terrifying. I spent years thinking of "wellness" as a luxury or a hobby, something for people with too much time. Now I see it as a mechanical necessity. If you don't schedule time for your wellness, you will be forced to make time for your illness. That’s a quote from somewhere, and man, does it hit different when you’re staring at a physical therapy bill for a back tweak you got while reaching for a bag of chips.
Friendship Requires a Strategy
Making friends as an adult is like trying to start a fire with wet matches. In college, you’re basically forced into intimacy. You live together, eat together, and have the same enemies (professors). Once you hit the real world, that "proximity effect" vanishes.
I wish I knew that you have to be the "annoying" friend who actually follows up. "We should grab coffee sometime" is the death knell of a relationship. It’s a polite way of saying "I like you, but not enough to look at my calendar." If you want to keep your people, you have to be specific. "Are you free next Tuesday at 6 PM?" is a terrifyingly vulnerable question because they might say no. But it’s the only way friendships survive the grind of career and family.
I’ve lost people I thought would be in my wedding party simply because we stopped being "convenient" to one another. It hurts. But it also taught me that friendship in adulthood is a discipline. It’s a choice you make every month to reach out, even when you’re tired, even when you have nothing "new" to report.

The Career Trap of "One Day"
There is this pervasive myth that we are all just one promotion away from being happy. We think, "If I can just get to Senior Manager, then I’ll have the authority to fix everything." Or "Once I make $120k, I’ll finally feel secure."
Here is the truth I wish I knew: The problems don't go away; they just change shape.
When you’re junior, your problem is that you have no power and no money. When you’re senior, your problem is that you have too much responsibility and no time. I’ve interviewed dozens of executives who are more miserable than the interns because they’ve climbed a ladder that was leaning against the wrong wall. They’re "successful" by every external metric, yet they haven't seen their kids on a weekday in three years.
We often mistake "more" for "better." We think a bigger team, a bigger budget, and a bigger title will fill the void. But if you don't like the day-to-day work of being a manager—the meetings, the conflict resolution, the endless emails—no amount of prestige will make it suck less. I wish I’d focused more on "lifestyle design" and less on "career advancement." I’d rather be a "nobody" with a Tuesday afternoon free to go to the movies than a "somebody" who is tethered to a laptop while on vacation in Hawaii.
The Mental Load of Comparison
Social media has turned our brains into comparison engines. You’re not just comparing yourself to your neighbor; you’re comparing your "behind-the-scenes" footage to everyone else’s "highlight reel."

I wish I knew that nobody actually has it figured out. Truly. I have friends who look like they’re living the dream—perfect travel photos, beautiful homes—who have called me crying because their marriage is falling apart or they’re $50,000 in credit card debt. The "perfection" you see online is a curated performance. It’s a brand, not a life.
When I stopped looking at what everyone else was doing, my anxiety dropped by about 40%. It’s hard. It’s a daily struggle to not feel "behind." But behind who? There is no master schedule for life. Some people get married at 22 and divorced by 30. Some find their soulmate at 45. Some people start their best business in their 60s (looking at you, Colonel Sanders). The timeline is a lie.
Practical Steps to Stop Wishing and Start Doing
If you’re sitting there thinking, "Yeah, I wish I knew all this ten years ago too," don't waste time on the regret. Regret is just a ghost that eats your future. Instead, look at where you are right now.
- Audit your "Obligations." Look at your calendar for the last two weeks. How many of those things did you actually want to do? How many were "shoulds"? Start ruthlessly cutting the things that drain you. If it isn't a "Hell Yes," it’s a "No."
- Fix your foundation. Stop looking for the "next big thing" and fix the small things. Drink more water. Sleep eight hours. Put $50 into an emergency fund. These aren't exciting, but they are the bedrock of a life that doesn't feel like it’s constantly on the verge of collapsing.
- Invest in "Low-Stakes" Connection. You don't need a three-course dinner to see a friend. Go for a walk. Call someone while you’re doing the dishes. Lower the barrier to entry for social interaction.
- Re-evaluate your "Success" Metrics. If your definition of success requires you to be stressed out 90% of the time, you need a new definition. What does a "good day" actually look like for you? Not a "productive" day, but a good one. Aim for more of those.
The most important thing I wish I knew is that life isn't something that happens to you once you get your act together. Life is what’s happening right now, while you’re waiting for things to get better. It’s the messy, boring, frustrating intervals between the big events. If you can learn to find some peace in the "in-between," you’ve already won.
Stop waiting for the "I wish I knew" moments to stop happening. They won't. You’ll be 70 and saying, "I wish I knew this at 50." That’s just the nature of growth. The goal isn't to be perfectly wise; it's to be slightly less dumb than you were yesterday.
Accept the mess. Forgive your younger self for not knowing things they couldn't possibly have known yet. Then, take a deep breath and go do something that makes you feel a little more human today. That’s really all any of us can do.
