What are the years from twenty to forty? Fettered and bound by personal and emotional relationships. That's bound to be. That's living. But later there's a new stage. You can think, observe life, discover something about other people and the truth about yourself. Life becomes real--significant. You see it as a whole. Not just one scene--the scene you, as an actor, are playing. No man or woman is actually himself (or herself) till after forty-five. That's when individuality has a chance.
