Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
Well done is better than well said.
Always desire to learn something useful.
Who seeks shall find.
The dog that trots about finds a bone.
Never complain and never explain.
Only the educated are free.
Without hard work, nothing grows but weeds.
I love the wry motto of the Paleontological Society, meant both literally and figuratively, for hammers are the main tool of our trade: Frango ut patefaciam - I break in order to reveal.
