I think this is a very interesting book, which helped me make some changes in my life. I was back and forth on a 4 or a 5 and since there is no 4.5 I went with 5, but it really doesn't matter, because it's a really good book. The method is effective and the book goes into great detail about how to use it and change your life. If you are interested in self-help books or learning new and creative methods for chaning yourself or clients, then it is a good resource to have.Terry M.
