But narcissism isn't just a combination of monumental self-esteem and rudeness. As a personality type, it ranges from a tendency to a serious clinical disorder, encompassing unexpected, even counterintuitive behavior. The Greek myth of Narcissus ends with the beautiful young man lost to the world, content to forever gaze at his own reflection in a pool of water. Real-life narcissists, however, desperately need other people to validate their own worth. "It's not so much being liked. It's much more important to be admired. Studies have shown narcissists are willing to sacrifice being liked if they think it's necessary to be admired," says Roy Baumeister, a social psychologist at Florida State University in Tallahassee.
