Only the educated are free.
Wherever you are - be all there.
Well done is better than well said.
Leap, and the net will appear.
The secret of getting ahead is getting started.
If you think you can do it, you can.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
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.
