I can, therefore I am.

Be thine own palace, or the world's thy jail.

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

If you think you can do it, you can.

Know or listen to those who know.

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

Leap, and the net will appear.

If you can dream it, you can do it.

You never know what motivates you.
