Do you agree that every person living on earth likes flattery and praise and wants to be to noticed?

Yes, I do agree, but I don't think everyone wants to be entirely noticed. Even when people say they don't care what others think, etc, everyone does a little bit, it's just part if being human. We all strive off praise, and positive comments from others, to make ourselves feel better. But that doesn't mean everyone wants too much attention upon themselves.! Good observation though!!! :)
