Be gentle to all and stern with yourself.

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

Leap, and the net will appear.

Expect problems and eat them for breakfast.

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

I can, therefore I am.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

By failing to prepare, you are preparing to fail.
