I can, therefore I am.

The wise does at once what the fool does at last.

If you think you can do it, you can.

Things do not happen. Things are made to happen.

The most effective way to do it, is to do it.

Leap, and the net will appear.

Be gentle to all and stern with yourself.

Well done is better than well said.

To be a good loser is to learn how to win.
