Query: Great book - One of the Best for simple techniques to overcome worry and stress

I hand out copies to friends. It is a classic with tons of examples from real-world people, not just clinical research and psychological theories. It doesn't take great scientific studies for people who live life to let us know what works. This confirms things you have discovered yourself.Recommend highly. You will find at least one or two things you can do to help you in your life.
