The most effective way to do it, is to do it.
You never know what motivates you.
Never complain and never explain.
If you've got a talent, protect it.
Always desire to learn something useful.
Well done is better than well said.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
Know or listen to those who know.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
