I hightly recommend this book. An easy, quick read that could change your life.

It is a good read, but as a behavioral nurse I wanted to use the material for group therapy and I found it very difficult to put the information into a lecture and discussion. The problem is that the information in the book is very scattered, with thoughts broken. It is like he was writing and over-edited it or didn't edit enough. However, I very much enjoyed it and have given the concepts much thought. It is a very small book but packed. By the way, there is no secret key to happiness. Ooops hope i didn't give anything away because there is much that can be learned about happiness. Highly recommended!
