I love to read about why we do the things we do. This is that book. It talks about the positive and negatives. Right at the end it talks a lot about unrecognized habits and ways we can find the driver of that habit. The problem I had was when they start trying to say that culpability is offset by unconscious habit. In the case of the man that murdered his wife. I could not get behind the idea of him not being guilty. But overall there are a lot of great methods outline for creating good habits and some good overall experiments that related to this area of study. If you ever wonder why you do what you do, I would recommend this book to you.
