Chasms are deceived by rumors of their depth.

I'm an optimist about love and a pessimist about the world.

Pessimism leans too much on the past, optimism on the future.

I'm an optimist about myself and a pessimist about the world.

The optimist's hope and the pessimist's despair: reciprocal illusions.

Don't worry! Something always goes wrong.

You can't think away your self-defeating thoughts; you have to dissolve them through action.

One can be a pessimist in thought but not in action.

The worse you think it will be, the better it is.
