The dog that trots about finds a bone.
It's always too early to quit.
Never complain and never explain.
Expect problems and eat them for breakfast.
Well done is better than well said.
To be a good loser is to learn how to win.
Go for it now. The future is promised to no one.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
