To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
After a storm comes a calm.
By failing to prepare, you are preparing to fail.
If you think you can do it, you can.
Never complain and never explain.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
Leap, and the net will appear.
You never know what motivates you.
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.
