You never know what motivates you.
Expect problems and eat them for breakfast.
Leap, and the net will appear.
The wise does at once what the fool does at last.
What you do today can improve all your tomorrows.
Never complain and never explain.
Only the educated are free.
I can, therefore I am.
The secret of getting ahead is getting started.
Quality is not an act, it is a habit.
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.
