Know or listen to those who know.

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

If you think you can do it, you can.

Be gentle to all and stern with yourself.

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

By failing to prepare, you are preparing to fail.

If you can dream it, you can do it.

Things do not happen. Things are made to happen.

Well done is better than well said.
