i think leary put it best… he wasnt talking of the meaning of life, but i think he is;

Happiness comes in small doses folks. It’s a cigarette butt, or a chocolate chip cookie or a five second orgasm. You come, you smoke the butt you eat the cookie you go to sleep wake up and go back to fucking work the next morning, THAT’S IT! End of fucking list! - Denis Leary [No Cure For Cancer]
