Optimism

"An optimist may see a light where there is none, but why must the pessimist always run to blow it out?"  Michael de Saint-Pierre

"A pessimist is someone, who, when confronted with two unpleasant choices, selects both." Anon

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