There's a lot about this book that I like, and that has helped me. Specifically the parts about breaking large daunting habits down into smaller achievable pieces, chaining habits together so that doing one makes you do others, and generally making habits enjoyable and convenient. There's a lot of practical advice. My only problem is that the book is framed from the perspective of an athlete who's striving for excellence. That's by no means unusual in self help books written by American men. I just don't derive a lot of motivation from a need to prove myself through competition.
