Optimists enrich the present, enhance the future, challenge the improbable and attain the impossible.

When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

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

Learn and grow all you can; serve and befriend all you can; enrich and inspire all you can.

The impossible often has a kind of integrity to it which the merely improbable lacks. How often have you been presented with an apparently rational explanation of something that works in all respects other than one, which is just that it is hopelessly improbable? Your instinct is to say, 'Yes, but he or she simply wouldn't do that.

The experienced mountain climber is not intimidated by a mountain -- he is inspired by it. The persistent winner is not discouraged by a problem -- he is challenged by it. Mountains are created to be conquered; adversities are designed to be defeated; problems are sent to be solved. It is better to master one mountain than a thousand foothills.
