Know or listen to those who know.

To know oneself, one should assert oneself.

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

If you've got a talent, protect it.

If you think you can do it, you can.

Never complain and never explain.

Things do not happen. Things are made to happen.

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

The secret of getting ahead is getting started.
