“People suffer.” That’s the first sentence of psychologist Steven Hayes’ latest book (he’s written 26), Get Out of Your Mind and Into Your Life: The New Acceptance and Commitment Therapy. His basic premise is: Accept pain and live your life. “My work is about a loving posture: Accept your history, feel your feelings, notice your thoughts, and carry all that forward down a path that you value that’s neither indulgence nor suppression,” Hayes said in a recent interview with Salon.com.
