“Still, Fritz was an optimist, and Karl was a pessimist, and that makes all the difference in the world.”
“The difference between an optimist and a pessimist? An optimist laughs to forget but a pessimist forgets to laugh.”
“The optimist thinks this is the best of all possible worlds. The pessimist fears it is true. ”
“The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true.”
“The world belongs to optimists. Pessimists are only spectators.”
“The optimist and the pessimist both die in the end, but each lives is life in a completely different way.”
