“HAPPINESS. — A butterfly, which when pursued, seems always just beyond your grasp; but if you sit down quietly, may alight upon you.”
— L. in The Daily Crescent (June, 1848)
Marcus Aurelius and Seneca both wrote that the best revenge is to exact no revenge at all. If someone treats you rudely and you respond with rudeness, you have not done anything but prove to them that they were justified in their actions.
