Query: I waited too long to read this book.

My wife was amazed that I,an avid 57 year old reader, had never read this book. I' glad that I finally did. It shoes the power of positive thinking and how this quality van make a major change in one' s life. My only complaint is that I thought they ending to be a bit abrupt. Otherwise great read!
