Be kind whenever possible. It is always possible.
You never know what motivates you.
After a storm comes a calm.
Who seeks shall find.
If you've got a talent, protect it.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
What you do today can improve all your tomorrows.
Know or listen to those who know.
Either you run the day or the day runs 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.
