Never complain and never explain.
Wherever you are - be all there.
Only the educated are free.
Do not weep do not wax indignant. Understand.
I can, therefore I am.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
If you can dream it, you can do it.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
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.
