If a man, notoriously and designedly, insults and affronts you, knock him down; but if he only injures you, your best revenge is to be extremely civil to him in your outward behaviour, though at the same time you counterwork him, and return him the compliment, perhaps with interest.
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 ChesterfieldA cheerful, easy, open countenance will make fools think you a good-natured man, and make designing men think you an undesigning one.
Lord ChesterfieldWhatever you do, do it to the purpose; do it thoroughly, not superficially. Go to the bottom of things. Any thing half done, or half known, is in my mind, neither done nor known at all. Nay, worse, for it often misleads.
Lord Chesterfield
