I can, therefore I am.

Without hard work, nothing grows but weeds.

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

Either you run the day or the day runs you.

Be gentle to all and stern with yourself.

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

Expect problems and eat them for breakfast.

Things do not happen. Things are made to happen.

Well done is better than well said.
