Never complain and never explain.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Things do not happen. Things are made to happen.
It's always too early to quit.
Who seeks shall find.
I can, therefore I am.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
Always desire to learn something useful.
I don't have the feeling of being motivated by anger, revenge or frustration.
