I can, therefore I am.

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

If you're going through hell, keep going.

Expect problems and eat them for breakfast.

Well done is better than well said.

By failing to prepare, you are preparing to fail.

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

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