What you do today can improve all your tomorrows.
If you've got a talent, protect it.
Without hard work, nothing grows but weeds.
Begin to be now what you will be hereafter.
After a storm comes a calm.
Never complain and never explain.
Be gentle to all and stern with yourself.
Only the educated are free.
To be a good loser is to learn how to win.
Always desire to learn something useful.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
