The dog that trots about finds a bone.
It's always too early to quit.
Leap, and the net will appear.
The secret of getting ahead is getting started.
Know or listen to those who know.
The most effective way to do it, is to do it.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
If you've got a talent, protect it.
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.'
