Be kind whenever possible. It is always possible.
Well done is better than well said.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
Never complain and never explain.
Know or listen to those who know.
The secret of getting ahead is getting started.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
Well-timed silence is the most commanding expression.
