It's always too early to quit.

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.

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

Things do not happen. Things are made to happen.

What you do today can improve all your tomorrows.

Never complain and never explain.

If you've got a talent, protect it.
