Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
Do not weep do not wax indignant. Understand.
Expect problems and eat them for breakfast.
Only the educated are free.
It's always too early to quit.
Always desire to learn something useful.
Know or listen to those who know.
Imagination! Imagination! I put it first years ago, when I was asked what qualities I thought necessary for success on the stage.
