Habits of pessimism lead to depression, wither achievement, and undermine physical health. The good news is that pessimism can be unlearned, and that with its removal depression, under-achievement, and poor health can be alleviated.
-Martin Seligman

I don't think of all the misery but of the beauty that still remains.
-Anne Frank

Consult not your fears but your hopes and your dreams.
Think not about your frustrations, but about your unfulfilled potential.
Concern yourself not with what you tried and failed in, but with what it is still possible for you to do.
-Pope John XXIII
