I purchased this book 4 years ago and I have read it about 5 times. Not only have I read it but I have also studied it and applied it to my own life. I love this book and its one I always recommened to friends/colleagues who are taking their first steps into personal development, You see the beauty of this book is that it does not go too deep that you lose the meaning of what is being said. It's an easy read, loads of points that make clear sense but that you never really thought about. A must , and if applied will no doubt make you a better person.
