Never complain and never explain.
Well done is better than well said.
If you think you can do it, you can.
Know or listen to those who know.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
Go for it now. The future is promised to no one.
To be a good loser is to learn how to win.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
