Money doesn't buy happiness because when we try to treat ourselves, we can end up spoiling ourselves, ruining the enjoyment of everyday pleasures like a chocolate bar, says Wired Science. "Because money allows us to enjoy the best things in life—we can stay at expensive hotels and eat exquisite sushi and buy the nicest gadgets—we actually decrease our ability to enjoy the mundane joys of everyday life." Examples include sunny days, cold beers, and chocolate bars. "And since most of our joys are mundane—we can’t sleep at the Ritz every night—our ability to splurge actually backfires."
