It's always too early to quit.
Only the educated are free.
Leap, and the net will appear.
Know or listen to those who know.
I can, therefore I am.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
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.
