Wherever you are - be all there.
Well done is better than well said.
What you do today can improve all your tomorrows.
If you're going through hell, keep going.
Never complain and never explain.
Know or listen to those who know.
Either you run the day or the day runs you.
Who seeks shall find.
If you've got a talent, protect it.
The one phrase you can use is that success has a thousand fathers, and failure is an orphan.
