If you can dream it, you can do it.
Wherever you are - be all there.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
The secret of getting ahead is getting started.
The wise does at once what the fool does at last.
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.
