Eric Berne originally described life positions, which are basic beliefs about the self and others that justify behavior. He delineated four life positions: "I'm OK, You're OK" refers to those with mostly positive experiences who can solve problems easily; "I'm not OK, You're OK" refers to depressives who believe others are OK; "I'm OK, You're not OK" refers to paranoids who distrust others; and "I'm not OK, You're not OK" refers to those who feel life is not worth living. Each position is associated with different personality traits and is formed from childhood experiences.
