Most people are just greeedy, they crave the things "they cannot have" because others are craving it. An on going competition to be "the Man" so to speak. It's a monkey see monkey do kind of behavior. Deep down they do not passionately desire those things/that person. It's a competitive mindset to be better than, or maybe be accepted, whatever, I don't know! Once they get their hands on it, there are no real sparks, no explosiveness, no passion. Life is still the same and they remain the same (or get worst). That individual or object hasn't changed a thing. Long story short..... Don't believe the Hype!
Don't get me wrong having nice things are Great! But there is nothing like knowing what you need and getting it..... in return keeping and loving it while LIVING to cherish it.
