If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
If you think you can do it, you can.
Be kind whenever possible. It is always possible.
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.
