Query: Self Hypnosis WORKS

A wonderful book that could change your life . . .Self-hypnosis is subtle but very real. At first, it's hard for some to believe that the mind has the power to change life for the better, but self hypnosis WORKS. To prove it, keep a short daily diary for a month or two at the onset of this program. Log what you hope to change, and then jot down a sentence or two every day to note any improvement in your life. The power of your mind will amaze you.I particularly like the added chapter on how to deal with stress, and Gail Sheey's introduction is excellent.Thank you, Dr. Fisher.
