To be a good loser is to learn how to win.
If you can dream it, you can do it.
Be kind whenever possible. It is always possible.
Well done is better than well said.
Never complain and never explain.
If you've got a talent, protect it.
It's always too early to quit.
Things do not happen. Things are made to happen.
Do not weep do not wax indignant. Understand.
Expect problems and eat them for breakfast.
