A pessimist is a well-informed optimist.

I'm a pessimist. But I'm a pessimist with a sense of responsibility.

But you know, I'm the negative-Nancy, curmudgeon, glass-half-empty-with-a-leak-in-it guy - which is basically the fuel that fires me up anyway. Without that, we wouldn't have me.

Pessimism is a form of mental dipsomania; it disdains healthy nourishment, indulges in the strong drink of denunciation, and creates an artificial dejection which thirsts for a stronger draught.

No man ever believes that the Bible means what it says: he is always convinced that it says what he means.

The more things a man is ashamed of, the more respectable he is.
