'Much of the "self-esteem movement" actually encourages narcissim, or the belief that one is better and more important than anyone else. Narcissism is a very negative personality trait linked to aggression and poor relationships with others. Somehow we've developed the notion that it's not OK to have a few insecurities, but it is OK to think you're the greatest and everyone else should get out of your way.'
