If you think you can do it, you can.
It's always too early to quit.
Either you run the day or the day runs you.
Who seeks shall find.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
Know or listen to those who know.
Without hard work, nothing grows but weeds.
Never complain and never explain.
I can, therefore I am.
We have, I fear, confused power with greatness.
