Always desire to learn something useful.
What you do today can improve all your tomorrows.
It's always too early to quit.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
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.'
