Lessons Learned at 30: What I Wish I’d Known in My Twenties

At 25, I thought I had it figured out. At 30, I realize I was just getting started.

Five years ago, I wrote an article about things I wished I’d started earlier in life. I was in my mid-twenties, already reflecting on “regrets” (even though I claimed to have none). Looking back now, I was onto something—but I didn’t yet understand why these things mattered.

Now, half a decade later and on the other side of my twenties, here’s what I’ve learned about those same five lessons—updated with the wisdom that only comes from actually living them.

What I said at 25: “Stop caring so much about what other people think. Ask yourself who really matters and focus on doing what brings you joy.”

What I know now at 30: I said it, but I didn’t do it. Not really.

At 25, I was still editing myself in conversations. Still second-guessing my career choices. Still asking “what will they think?” before making moves.

At 30, I’ve learned that the people whose opinions actually matter? They’re the ones who want you to bet on yourself, not play it safe.

Here’s the shift: It’s not about “not caring” what anyone thinks. It’s about choosing whose opinions get a vote in your life decisions.

Your mother who’s worried about stability? She gets a voice, but not a veto.Your friend who’s jealous of your career pivot? They don’t even get a seat at the table.The stranger on the internet who thinks you’re doing it wrong? Noise.

What I’d tell my 25-year-old self: The people who matter will support your bets, even when they don’t fully understand them. Everyone else? They’re watching from the sidelines while you’re playing the game.

What I said at 25: “Put more towards my health and wealth. Nourish yourself, move your body, save your pennies.”

What I know now at 30: Health and wealth aren’t separate goals—they’re the same asset with different timelines.

At 25, I worked out to look a certain way. I saved money out of fear.

At 30, I work out because I’m training my body to do hard things (like run 100 miles). I save money because it buys me freedom—the freedom to quit a job that drains me, to invest in my business, to take a month off if I need to.

The real lesson? Both health and wealth are about building capacity for the life you actually want.

Every workout is a bet on your future self. Every dollar saved is permission to take a risk later.

What changed: I stopped treating my body like a project to fix and started treating it like a tool I’m training for a specific purpose. Same with money—it’s not about being “rich,” it’s about having options.

What I’d tell my 25-year-old self: Those “silly purchases” you regret? You needed them to learn what actually matters. But start investing in experiences, not things. And for god’s sake, open that retirement account now.

What I said at 25: “I wasted years overthinking before pulling the plug. Take action before you feel ready.”

What I know now at 30: I was right about starting before I felt ready. What I didn’t know? Starting is only 10% of the work.

At 25, I thought launching my business was the hard part.

At 30, I realize that starting was the easy part. Building something sustainable? That’s the real work.

I finally taught my first yoga class months after certification. I started my podcast years after thinking about it. But the pattern I’ve learned? The people who succeed aren’t the ones who start with the most confidence—they’re the ones who keep going when it gets hard.

What changed: I stopped romanticizing the “launch” and started focusing on the long game. Consistency beats intensity. Showing up for two years beats going viral once.

What I’d tell my 25-year-old self: You’re right to start before you’re ready. But also know that five years from now, you’ll still be building this thing. And that’s not a failure—that’s how it works.

What I said at 25: “Connection is all that we have. Show those you love how much you care.”

What I know now at 30: I wrote this, but I still prioritized work over relationships. I still canceled plans to chase deadlines. I still took people for granted.

At 30, I’ve lost friends I wish I’d invested in. I’ve watched relationships fade because I assumed they’d always be there.

Here’s what I’ve learned: Relationships don’t wait for you to “have more time.” They either grow or they fade.

The friends who stuck around through my twenties? The ones I showed up for, even when it was inconvenient. The ones I texted back. The ones I made time for.

What changed: I stopped treating relationships like something I’d “get to later” and started treating them like the most important work I do. I call people back. I show up. I say “I love you” more.

What I’d tell my 25-year-old self: That promotion you’re chasing? You’ll barely remember it in five years. The friend you’re too busy to see? You’ll wish you’d made time.

What I said at 25: “Don’t let fear stop you from following your dreams. Take the leap.”

What I know now at 30: I was thinking about bungee jumping and trail races. Now I realize the real chances aren’t the Instagram-worthy adventures—they’re the quiet bets that change your life trajectory.

At 25, I took chances that looked bold: traveling abroad, running ultras, hosting retreats.

At 30, I’ve learned that the biggest chances are the ones no one sees:

What changed: I stopped chasing impressive risks and started taking meaningful ones. The kind that don’t get likes but change everything.

What I’d tell my 25-year-old self: That bungee jump you skipped? You were right to skip it. Save your courage for the bets that actually matter.

Build a life that doesn’t require permission.

At 25, I was still asking: Can I do this? Should I do this? What if it doesn’t work?

At 30, I’ve learned to ask: What if it does work? And who said I needed permission anyway?

The biggest shift from 25 to 30 wasn’t what I did—it was deciding I didn’t need to wait for anyone to tell me I was allowed to do it.

If you’re in your mid-twenties reading this: You’re not behind. You’re right on time. But here’s what I wish someone had told me:

The things you’re overthinking right now? Start them anyway.

The relationships you’re taking for granted? Show up before it’s too late.

The bets you’re too scared to make? Five years from now, you’ll wish you’d made them today.
