Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
The dog that trots about finds a bone.
Never complain and never explain.
Expect problems and eat them for breakfast.
Always desire to learn something useful.
If you're going through hell, keep going.
I can, therefore I am.
Well done is better than well said.
To be a good loser is to learn how to win.
