I can, therefore I am.

If you're going through hell, keep going.

The secret of getting ahead is getting started.

If you think you can do it, you can.

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

The dog that trots about finds a bone.

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

You never know what motivates you.

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