I think we all just want to feel like we are a part of something great. They say you haven't found anything to live for until you find something worth dying for. :-)

Something is always missing. I agree with you. But is perfection possible for humans? What it is? You didn't know at last what it is. Maybe it's the reason of life. We or should I better say humanity is searching for it. Maybe there is an easy answer, but that answer we won't like or accept.
