A Quote by Philip Dormer Stanhope, Lord Chesterfield on learning, people, and privacy

Never seem wiser, nor more learned, than the people you are with. Wear your learning, like your watch, in a private pocket, and do not pull it out and strike it merely to show you have one. If you are asked what o'clock it is, tell it, but do not proclaim it hourly and unasked, like the watchman.
