Keep your own secret, and get out other people's. Keep your own temper, and artfully warm other people's. Counterwork your rivalswith diligence and dexterity, but at the same time with the utmost personal civility to them: and be firm without heat.
Lord ChesterfieldObserve it, the vulgar often laugh, but never smile, whereas well-bred people often smile, and seldom or never laugh. A witty thing never excited laughter, it pleases only the mind and never distorts the countenance.
Lord ChesterfieldSmooth your way to the head through the heart. The way of reason is a good one: but it is commonly something longer, and perhapsnot so sure.
Lord Chesterfield
