5.0

This book makes James Clear's "Atomic Habits" book feel like a pamphlet, although I'm not sure which one will eventually have a bigger impact on people's behaviour. There are A LOT of actionable insights in this book which is why I recommend taking the authors suggestion seriously and reading this book through in chunks with practice periods in between.

The book is well written, backed up by research (the author is a lecturer on willpower at Stanford University) and does a great job of explaining the evolutionary process that has shaped our behavioural mechanics. It also expands on a variety of topics outside the personal realm, like neuromarketing, governmental policies etc.

Out of the books I've read on the same topic it clearly tops The Marshmallow Test and even The Power of Habit (which was great, but a little too general) and stands in tie with Atomic Habits as the latter is one of the most actionable books I've read.
