You know, it’s a funny thing, you can smoke yourself to death, drink yourself to death, work yourself to death, and even eat yourself to death. But that’s all acceptable. The only thing you can’t do medically is screw yourself to death and yet that’s where they put all the obstacles.
— Jules Segal, in Mario Puzo’s The Godfather
How one lives is so far distant from how one ought to live, that he who neglects what is done for what ought to be done, sooner effects his ruin than his preservation; for a man who wishes to act entirely up to his professions of virtue soon meets with what destroys him among so much that is evil.
— Niccolò Machiavelli, The Prince
