Be wiser than other people, if you can; but do not tell them so. – Lord Chesterfield
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 merely pull it out and strike it merely to show that you have one. – Lord Chesterfield
Good humor is the health of the soul, sadness is its poison. – Lord Chesterfield
Style is the dress of thoughts; and let them be ever so just, if your style is homely, coarse, and vulgar, they will appear to as much disadvantage, and be as ill received, as your person, though ever so well-proportioned, would if dressed in rags, dirt, and tatters. – Lord Chesterfield
