Make somebody happy today. Mind your own business.

In two brisk imperatives, the line pairs outward kindness with inward restraint. “Make somebody happy today” urges practical, immediate benevolence—small acts that improve another person’s day without waiting for ideal circumstances. “Mind your own business” supplies the counterweight: a warning against meddling, gossip, and moral busybodying that often masquerade as concern. Together they express a commonsense ethic associated with advice-column wisdom: do good where you can, but respect boundaries and let others manage their own lives. The humor of the abrupt second sentence sharpens the lesson, suggesting that many social conflicts would ease if people redirected energy from judging others to helping them.
