The pleasure principle is a psychoanalytic concept, originated by Sigmund Freud. The pleasure principle states that people seek pleasure and avoid pain, i.e., people seek to satisfy biological and psychological needs. The counterpart is the reality principle, which defers gratification when necessary. An individual's id follows the pleasure principle and rules early life, but, as one matures, one learns the need to endure pain and defer gratification, because of the exigencies and obstacles of reality.
