I can, therefore I am.

What you do today can improve all your tomorrows.

It's always too early to quit.

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

Either you run the day or the day runs you.

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

Things do not happen. Things are made to happen.

If you've got a talent, protect it.

Be gentle to all and stern with yourself.
