Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
If you're going through hell, keep going.
Well done is better than well said.
I can, therefore I am.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
It is in vain to hope to please all alike. Let a man stand with his face in what direction he will, he must necessarily turn his back on one half of the world.
