You never know what motivates you.
Wherever you are - be all there.
Leap, and the net will appear.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
I can, therefore I am.
Be thine own palace, or the world's thy jail.
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.
