Both optimists and pessimists contribute to our society. The optimist invents the airplane and the pessimist the parachute.
A pessimist sees only the dark side of the clouds, and mopes; a philosopher sees both sides, and shrugs; an optimist doesn't see the clouds at all - he's walking on them.
Leonard Louis Levinson
In the long run the pessimist may be proved right, but the optimist has a better time on the trip.
Daniel L. Reardon
Between the optimist and the pessimist, the difference is droll. The optimist sees the doughnut; the pessimist the hole!
One of the things I learned the hard way was that it doesn't pay to get discouraged. Keeping busy and making optimism a way of life can restore your faith in yourself.
I am a big believer that eventually everything comes back to you. You get back what you give out.
If they can make penicillin out of moldy bread, they can sure make something out of you.
An optimist is a person who sees a green light everywhere, while a pessimist sees only the red stoplight.
No pessimist ever discovered the secrets of the stars, or sailed to an uncharted land, or opened a new heaven to the human spirit.
Life is too short to spend your precious time trying to convince a person who wants to live in gloom and doom otherwise. Give lifting that person your best shot, but don't hang around long enough for his or her bad attitude to pull you down. Instead, surround yourself with optimistic people.
I'm an optimist and I believe that I'll find someone I'll love more than I've been able to love before.
I always like to look on the optimistic side of life, but I am realistic enough to know that life is a complex matter.
An optimist is someone who can look at a situation, assess if for what it really is, and if it's negative, find a way to see at least parts of it in a positive light.

"Well-being can be built on what you can do and on what we can enjoy, never built on thinking about what cannot be done and what can no longer be enjoyed."
JoAnn Le Maistre
"Optimists see failures as learning experiences, as challenges to modify their approach. Pessimist take failures personally, interpreting them as evidence of some deep-seated character flow."
