There is overwhelming evidence that YOUR ERRONEOUS ZONES, one of the fastest-selling books in history, is also one of the most practical self-actualization books ever written, as Dr. Dyer's own remarkable success story demonstrates. A practicing therapist and counselor, he has followed his own advice to become a coast-to-coast celebrity and, in a very short time, has appeared on more than 700 radio and television shows. His message is simple and direct.
