I can, therefore I am.
Never complain and never explain.
Know or listen to those who know.
The secret of getting ahead is getting started.
After a storm comes a calm.
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.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
