Atomic Habits

I like this book most when I treat it less like self-help and more like product design for my own behavior. The useful idea is not "try harder" — it's make the right action obvious, easy, and repeatable.

The parts on environment design stuck with me because they remove so much drama from discipline. If a habit keeps failing, the honest question is usually not "what's wrong with me?" It's "what system keeps making the wrong thing easier?"
