"changed my life"
scientific; practical
the fact that the authors take time to explain the fundamentals of psychology and physiology of willpower.
I like scientific books. I particularly enjoy books that provide research based insights into problems. I am not a fan of conclusions drawn from a single person's experiences (there are many books out there like that). So, I really enjoyed this book. If you are looking for a bulleted list kind of thing to strengthen your willpower, you will have to wait until the end. But, then you should understand that the book is really about understanding why we as human beings use our willpowers as we use them. I used the scientific facts and insights in this book to craft a strategy for changing many bad habits that I had and I succeeded.
