I can, therefore I am.

If you think you can do it, you can.

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

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

If you can dream it, you can do it.

Leap, and the net will appear.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

Wherever you are - be all there.
