If you're going through hell, keep going.
Well done is better than well said.
You never know what motivates you.
If you can dream it, you can do it.
Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
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.
