I can, therefore I am.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

Leap, and the net will appear.

It's always too early to quit.

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

If you think you can do it, you can.

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

Expect problems and eat them for breakfast.
