As we change what you say and do, we will change what you think and feel. --Andrew Salter Welcomed as a revolutionary and effective approach to improve people's mental health and help them find happiness when it was first published in 1949, Andrew Salter's Conditioned Reflex Therapy introduced both the fundamental ideas of behavior therapy and many techniques still practiced today. This classic guide, which is perhaps the first self-help book, includes specific methods for assertion, getting in touch with your feelings, relaxation, and using imagery to overcome phobias, anxieties, and depression. Captivating and direct, it still seems fresh, though it also conveys the spirit of New York City in the late 1940s. It vividly evokes the timeless concerns of people striving for happiness and self-actualization amid the energy of post-war America, the hum of traffic, the buzz of restaurants and cocktail parties. It will teach you how to be more aware of your feelings and more authentic in your life, and thereby to be happier and more fulfilled in your relationships and career.
