I never saw a pessimistic general win a battle.

If you get up in the morning and think the future is going to be better, it is a bright day. Otherwise, it's not.

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'd rather be an optimist and a fool than a pessimist and right.

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.
