The book provided a good summary in a concise manner. As I read this book, I wondered about the author's credentials...is she a psychologist, a counselor, a researcher? When I checked her background, what I found is she is a "prolific writer" and a poet. Although I was a bit skeptical, there were several things in the book that I found to be relevant in my experience and I will use to improve my life experience. For me, more direct references to the sources would have made the book more credible.
