Many an optimist has become rich by buying out a pessimist.
Robert G. Allen

Optimism is not inherently a superior way of viewing the world. Certainly doctors will say it might be better for one's physical health to be an optimist. But, morally speaking it may not be appropriate in certain circumstances.
Todd Solondz

Perhaps believing in good design is like believing in God, it makes you an optimist.
Terence

The difference between an optimist and a pessimist? An optimist laughs to forget, but a pessimist forgets to laugh.
Tom Bodett

The farmer has to be an optimist or he wouldn't still be a farmer.
Will Rogers

The man who is a pessimist before 48 knows too much; if he is an optimist after it, he knows too little.
Mark Twain

The optimist proclaims that we live in the best of all possible worlds, and the pessimist fears this is true.
James Branch Cabell

The optimist thinks this is the best of all possible worlds. The pessimist fears it is true.

The point of living and of being an optimist is to be foolish enough to believe the best is yet to come.
Peter Ustinov

There is only one optimist. He has been here since man has been on this earth, and that is man himself. If we hadn't had such a magnificent optimism to carry us through all these things, we wouldn't be here. We have survived it on our optimism.
Edward Steichen

Which is, I'm an optimist that two people can be together to work out their conflicts. And that commitment, I think, might be what love is, because they both grow from their relationship.
Garry Shandling

With optimism, you look upon the sunny side of things. People say, 'Studs, you're an optimist.' I never said I was an optimist. I have hope because what's the alternative to hope? Despair? If you have despair, you might as well put your head in the oven.
Studs Terkel

Yet creeds mean very little, Coth answered the dark god, still speaking almost gently. The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true.
James Branch Cabell

You can do anything you think you can. This knowledge is literally the gift of the gods, for through it you can solve every human problem. It should make of you an incurable optimist. It is the open door.
Robert Collier
