If you're going through hell, keep going.
Expect problems and eat them for breakfast.
If you can dream it, you can do it.
Only the educated are free.
Things do not happen. Things are made to happen.
I can, therefore I am.
After a storm comes a calm.
The dog that trots about finds a bone.
If you think you can do it, you can.
The secret of getting ahead is getting started.
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.
