Good manners, to those one does not love, are no more a breach of truth, than "your humble servant," at the bottom of a challengeis; they are universally agreed upon, and understand to be things of course. They are necessary guards of the decency and peace of society.
Lord ChesterfieldThere are some occasions in which a man must tell half his secret, in order to conceal the rest: but there is seldom one in which a man should tell it all.
Lord ChesterfieldCultivate the habit of thinking ahead, and of anticipating the necessary and immediate consequences of all your actions.... Likewise in your pleasures, ask yourself what such and such an amusement leads to, as it is essential to have an objective in everything you do. Any pastime that contributes nothing to bodily strength or to mental alertness is a totally ridiculous, not to say, idiotic, pleasure.
Lord ChesterfieldObserve any meetings of people, and you will always find their eagerness and impetuosity rise or fall in proportion to their numbers.
