It's always too early to quit.
Always desire to learn something useful.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
Who seeks shall find.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
It often takes more courage to change one's opinion than to keep it.
