You should not only have attention to everything, but a quickness of attention, so as to observe at once all the people in the room--their motions, their looks and their words--and yet without staring at them and seeming to be an observer.
Lord ChesterfieldIf you wish particularly to gain the good graces and affection of certain people, men or women, try to discover their most striking merit, if they have one, and their dominant weakness, for every one has his own, then do justice to the one, and a little more than justice to the other.
Lord ChesterfieldA man of the best parts and greatest learning, if he does not know the world by his own experience and observation, will be very absurd, and consequently very unwelcome in company. He may say very good things; but they will be probably so ill-timed, misplaced, or improperly addressed, that he had much better hold his tongue.
Lord Chesterfield
