If you've got a talent, protect it.
Know or listen to those who know.
Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
To be a good loser is to learn how to win.
Finish last in your league and they call you idiot. Finish last in medical school and they call you doctor.
You know what they call the fellow who finishes last in his medical school graduating class? They call him 'Doctor.'
