Most of this book presents a clear and useful framework for thinking about and developing habits, or minimising behaviours you'd rather avoid. The style is very much the modern "originally written for a blog" one, and thankfully his anecdotes are mostly taken from others as I get the impression I'd find him quite intolerable in person.

Something that might have been useful is discussion of what happens when your brain's dopamine response is atypical, do you just crank these strategies to 11? Are there other complimentary approaches? It's perhaps understandable that the book assumes a neurotypical reader, but it also seems like this is exactly the sort of book that might be sought out by someone who isn't.

Still, there's a lot of useful stuff in here and I'm looking forward to putting it into practice.
