Either you run the day or the day runs you.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
Never complain and never explain.
Be kind whenever possible. It is always possible.
Wherever you are - be all there.
Always desire to learn something useful.
If you've got a talent, protect it.
Without hard work, nothing grows but weeds.
Beauty is the first test: there is no permanent place in the world for ugly mathematics.
