Ask someone who doesn't like you. They'll at least be honest about it. You can come up with the answer yourself. Here are some thoughts: Do you constantly talk about yourself to others and never ask how their life is going? Do you treat people unkindly or consider other people stupid and you are much more intelligent? Do you ignore other's opinions on certain subjects? Do you order people around and don't care what their likes or dislikes are? Are you argumentative with others over most subjects in a conversation? Do you always have to be right? Those above are but a few. If you have 1 or more of these then you need to sit up and fly right! Most of us have a little narcissism going on inside ourselves, but most people take time out and try to balance it.
