In other words, don’t be like Seinfeld’s night guy and morning guy. “Every guy has two guys living inside him - night guy and morning guy. Night guy constantly screws morning guy over - stays out til 3am, spends all his money on booze… then morning guy has to go to work with a hangover and can’t afford an oil change. And morning guy can’t do a thing about it, except lose his job so night guy doesn’t have any money to go out.”
