To be a good loser is to learn how to win.
You never know what motivates you.
Never complain and never explain.
Expect problems and eat them for breakfast.
Only the educated are free.
Without hard work, nothing grows but weeds.
Things do not happen. Things are made to happen.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
Although you may spend your life killing, You will not exhaust all your foes. But if you quell your own anger, your real enemy will be slain.
If you desire ease, forsake learning.
