Never complain and never explain.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
What you do today can improve all your tomorrows.
If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
Only the educated are free.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
A mathematician is a person who can find analogies between theorems a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
