Mr. Linderman: You see, I think there comes a time when a man has to ask himself whether he wants a life of happiness or a life of meaning.
Nathan Petrelli: I'd like to think I have both.
Mr. Linderman: Can't be done. Two very different paths. I mean, to be truly happy, a man must live absolutely in the present. And with no thought of what's gone before, and no thought of what lies ahead. But, a life of meaning... A man is condemned to wallow in the past and obsess about the future. And my guess is that you've done quite a bit of obsessing about yours these last few days. - HEROES
