If you think you can do it, you can.
The wise does at once what the fool does at last.
After a storm comes a calm.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
Leap, and the net will appear.
To know oneself, one should assert oneself.
You never know what motivates you.
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.
