If you're going through hell, keep going.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
I can, therefore I am.
Wherever you are - be all there.
If you think you can do it, you can.
Expect problems and eat them for breakfast.
Quality is not an act, it is a habit.
If you can dream it, you can do it.
Always desire to learn something useful.
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.
