Happiness. We're tearing our hair out to try to find a definition of it, for heaven's sake. Is it joy? People will tell you that it isn't, that joy is a fleeting emotion, a moment of happiness, which is always welcome, mind you. And then what about pleasure, huh? Oh, yes, that's easy, everybody knows what that is, but there again it doesn't last. But is happiness not the sum total of lots of small joys and pleasures, huh?
