It's always too early to quit.

What you do today can improve all your tomorrows.

Without hard work, nothing grows but weeds.

I can, therefore I am.

Do not weep do not wax indignant. Understand.

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

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

Know or listen to those who know.

Expect problems and eat them for breakfast.
