The dog that trots about finds a bone.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
To be a good loser is to learn how to win.
If you can dream it, you can do it.
Only the educated are free.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
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.
