I can, therefore I am.
To know oneself, one should assert oneself.
To be a good loser is to learn how to win.
Know or listen to those who know.
Either you run the day or the day runs you.

Go for it now. The future is promised to no one.
You never know what motivates you.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
