Always borrow money from a pessimist, he doesn't expect to be paid back.

An optimist thinks that this is the best possible world. A pessimist fears that this is true.

Both optimists and pessimists contribute to our society. The optimist invents the airplane and the pessimist the parachute. --Gil Stern

A pessimist is one who makes difficulties of his opportunities, and an optimist is one who makes opportunities of his difficulties. --Harry Truman

No pessimist ever discovered the secrets of the stars, or sailed to an uncharted land, or opened a new heaven to the human spirit. --Helen Keller

The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.

A pessimist is just an optimist with life experience
