Honest error is to be pitied, not ridiculed. — Lord Chesterfield. British politician, diplomat and writer
Wit is so shining a quality that everybody admires it; most people aim at it, all people fear it, and few love it unless in themselves.
Never seem more learned than the people you are with. Wear your learning like a pocket watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked.
