Do not weep do not wax indignant. Understand.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
You never know what motivates you.
Never complain and never explain.
Only the educated are free.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
If you can dream it, you can do it.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
