To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.

Expect problems and eat them for breakfast.
If you've got a talent, protect it.
The dog that trots about finds a bone.
You never know what motivates you.
I can, therefore I am.
