I never saw a pessimistic general win a battle.

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.

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

A pessimist sees the difficulty in every opportunity; an optimist sees the opportunity in every difficulty.

Every man should ask himself each day whether he is not too readily accepting negative solutions.

A pessimist is a well-informed optimist.
