Always desire to learn something useful.
The dog that trots about finds a bone.
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.
If you think you can do it, you can.
Never complain and never explain.
I can, therefore I am.
What you do today can improve all your tomorrows.
The object of pure physics is the unfolding of the laws of the intelligible world the object of pure mathematics that of unfolding the laws of human intelligence.
