The Dopamine Code Is Here
What it is, why I wrote it, and how to get it — in paperback, ebook, or the audiobook I narrated myself.
For most of my career, this science lived in pieces — in the room with the people I work with, in my own head, and in the articles I’ve published one idea at a time. Today, for the first time, it lives in one place: between two covers, where anyone can pick it up.
The Dopamine Code: How to Rewire Your Brain for Happiness and Productivity, published by Simon & Schuster, is out today — available wherever books are sold. Let me tell you, briefly, what it is and why I wrote it.
Dopamine has become the most blamed and least understood molecule in modern life. We call it the pleasure chemical. It is not. It is the molecule of pursuit — the engine of wanting, chasing, anticipating — and the modern world has learned to hijack it faster than your brain can recalibrate.
It is the molecule of pursuit — the engine of wanting, chasing, anticipating — and the modern world has learned to hijack it faster than your brain can recalibrate.
The pleasure of actually arriving runs on a different, quieter system entirely. Once you can see that distinction, an enormous amount about modern life starts to make sense — including why it can feel like running faster and enjoying less.
The book does two things. First, it makes the science clear: no jargon, no shame, no blaming you for a system that was trained into you. Then it hands you the tools — how to read your own reward patterns, how to reset a brain that has been overstimulated into numbness, and how to build what I call a dopamine menu: a structured way of living that gives back genuine satisfaction instead of the next empty chase.
I wrote it for the person who has done the reading, tried the apps, and still feels like their own brain is working against them. You are not broken. Your dopamine system is doing exactly what it was trained to do. The work is retraining it — and that work can be learned.
There is also an audiobook. I narrated it myself, which was its own wonderful experience — reading years of work aloud, one chapter at a time.
If the book lands for you, the most useful thing you can do for it is small and real: tell one person who needs it, and leave an honest review. New books find their footing in the first weeks, and a few words from a real reader carry further than any amount of marketing.
Thank you for being here, and for reading these letters while the book was still becoming itself. Now it is yours.
