"Acting is the expression of a neurotic impulse. It's a bum's life. Quitting acting, that's the sign of maturity"

Marlon Brando's quote recommends that acting is a kind of unstable behavior, and that a life of acting is not a desirable one. He indicates that stopping acting suggests maturity, suggesting that it is a more responsible and stable way of life. This might be analyzed as Brando's viewpoint that actors are frequently viewed as immature and careless, and that giving up acting is a way to prove that a person can making responsible decisions. It might also be interpreted as Brando's opinion that acting is a hard and unstable way of life, which quitting suggests maturity due to the fact that it is a hard decision to make. In either case, Brando's quote suggests that stopping acting suggests maturity and obligation.
