Think clearly. Build freely. Adapt faster.

I’m Donn Felker. I’ve spent 25+ years shipping software: books on Android development and freelancing, seven years co-hosting the Fragmented Podcast, and work for companies you know: Google, Disney, American Express, and a whole lot more. These days I lead AI adaptation at Polygon and build my own products on the side.

Here’s what all of it taught me: clear thinking is the root skill of a self-directed life.

Not hustle. Not the newest tool. Your psychology is the game. Everything else is downstream.

That’s what this newsletter is about. How to think clearly, stay disciplined, and stay valuable while AI rewrites the rules of how we work and live. Some weeks that’s the psychology of focus. Some weeks it’s building with AI agents. Some weeks it’s working for yourself and designing a life you actually own.

One deep piece most weeks. Written to be read, not skimmed. No fluff, no spam, unsubscribe whenever.
