Linderman: There comes a time when a man has to ask himself whether he wants a life of happiness or a life of meaning.
Nathan: I'd like to have both.
Linderman: Can't be done. Two very different paths. To be truly happy, a man must live absolutely in the present, no thought of what's gone before and no thought of what lies ahead. But a life with meaning, a man is condemned to wallow in the past and obsess about the future.
