It's always too early to quit.

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

What you do today can improve all your tomorrows.

Never complain and never explain.

If you're going through hell, keep going.

The dog that trots about finds a bone.

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

Do not weep do not wax indignant. Understand.

Know or listen to those who know.
