If you want to know the answer to the question the book title poses, read up to the first list of 7 items the author discusses. Everything after that is like a psychological "pump you up" journey. Honestly, I felt like I was being prepared to join a cult with a large portion of the items discussed in this book. Without a doubt, there are good points made in this book, but I think this book could be half its length. One good thing I will say is that this is a relatively easy read and it was easy to follow along.
