You’re not done yet


Think about who you were ten years ago.

Your priorities. Your certainties. The things you thought you’d never change your mind about. The identity you would have described if someone asked.

Now think about how much has shifted since then. Not just circumstances. You. The way you see the world. What matters. What doesn’t anymore.

If you’re honest, the change is probably significant. Maybe dramatic.

And yet.

If I asked you how much you expect to change in the next ten years, the answer would probably be: not that much. Maybe some refinements. Some growth around the edges. But fundamentally? You’re pretty much who you’re going to be.

This is what Harvard researchers call the End of History Illusion. The belief that right now, at this very moment, you’ve finally become the person you’ll be for the rest of your life.

Here’s what makes it worth paying attention to: it’s not a one-time realization. It’s running constantly, at every age, on a loop.

The person who thought they were done becoming at 25 changed dramatically by 35. And at 35, they thought they were done again. At 45, same thing. The illusion resets every time.

We have endless evidence of our own transformation. And we still can’t imagine more of it ahead.

This matters for the Success Trap because it’s part of why identity fusion feels so absolute.

“I don’t know who I am without this role.” That’s not just fear talking. It’s a cognitive limitation. Your brain literally struggles to project a transformed version of you into the future. So the current identity feels permanent, even when everything in your history says otherwise.

The trap feels like a life sentence because you can’t imagine the person who’s already free.

But here’s the permission in it:

You don’t need to see the whole path. The person who will navigate what’s ahead isn’t the person reading this right now. Future-you will have capacities, perspectives, and clarity that current-you doesn’t have access to yet.

You’ve always become someone new. You will again.

The question isn’t whether you’ll change. The research says you will, whether you expect to or not. The question is whether you’ll participate in that change intentionally, or just let it happen to you.

What's something you believed ten years ago that you've completely outgrown? Hit reply. I read every message.

This week: Think back to a belief or priority you held ten years ago that you’ve since outgrown. Something you were certain about then that you see differently now. Then ask: What am I certain about today that might shift in the next ten years? What identity am I gripping that future-me might hold more loosely?

You’re not done yet. You never were.

We've gotten very good at eliminating friction. One-click purchases. Algorithmic playlists. Instant everything. The entire tech economy is built on the premise that friction is the enemy, that smoother is better, that the goal is to remove every obstacle between you and what you want. And for some things, that's genuinely useful. But here's what I've started to notice: The easier something becomes, the less it seems to mean. The song that plays automatically doesn't land the same as the one...

There's a story about a martial arts student who approaches his teacher. "How long will it take me to master this craft?" The teacher considers him. "Ten years." The student nods, then leans forward. "But what if I practice twice as hard? What if I train every day, longer than anyone else? How long then?" The teacher smiles. "Twenty years." Most of us are the student. We believe that more effort solves everything. That if something isn't working, we just need to push harder. Stay later. Grind...

I was seventeen, sitting in a scholarship interview, and they asked me to share a quote that shaped how I saw the world. Without hesitation: "Those who don't build must burn." Ray Bradbury. Fahrenheit 451. And for years, I thought the quote was about ambition. About the importance of creating things, making your mark, leaving something behind. I wasn't totally wrong. But I wasn't seeing the whole picture either. What I understand now, a few decades later, is that the quote isn't really about...
