Maybe, we all are. Life is a pursuit for happiness. We want, crave and desire what makes us happy. And then we want more of it. Who gets up and wants nothing. We want gratification, satisfaction and all the love we can get. Humans want. If we weren't such greedy little buggers, our want would always be directed at the good of someone else. We don't realize how greedy we are because we associate greed with money, but, we can greed for food, for fame, for power, for beauty, for love, and endless other things. It isn't necessarily bad. Its what we are willing to do to satisfy our greed that makes it good or bad.
