It's always too early to quit.

Expect problems and eat them for breakfast.

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

What you do today can improve all your tomorrows.

Things do not happen. Things are made to happen.

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

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

You never know what motivates you.
