If you think you can do it, you can.

I can, therefore I am.

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

Well done is better than well said.

Things do not happen. Things are made to happen.

Be gentle to all and stern with yourself.

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

Leap, and the net will appear.

What you do today can improve all your tomorrows.
