Expect problems and eat them for breakfast.
Know or listen to those who know.
Always desire to learn something useful.
Well done is better than well said.
Either you run the day or the day runs you.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
The secret of getting ahead is getting started.
After a storm comes a calm.
You never know what motivates you.
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.
