I found this book well organized, clear, concise and quite enjoyably readable. Now I have a better grasp of why I can establish a new habit only to have it vanish in thin air months later. It has not only anecdotes to illustrate it's ideas but also clear explanations of the neurology behind the premises posited. At first I thought maybe I'd only read the first section about individual habits as that's what I'm concentrating on. It turns out I'm glad I didn't because the other two sections (Habits of Successful Organizations and Habits of Societies) both had valuable insights. If you're at all interested in personal habits, organizational psychology, or changing society this is worth the read.
