Money is not the narcissist's only compulsion. Many narcissists are compulsively orderly and clean. They may be addicted to intellect and knowledge, to maximal utilisation of time, to any strange outcome of an obsessive streak. Some suffer from compulsive ticks and more complex repetitive, ritualistic movements. They might even become criminally compulsive, kleptomaniacs, for instance.
Narcissists are very misleading.
They are possessed of undeniable personal charm and, usually, of sparkling intellect. Other people tend to associate these traits with maturity, authority and responsibility. As far as narcissists are concerned, this association is a grave mistake. They lack many adult skills and tend to rely on people around them to make up for these deficiencies. That people will obey and comply is taken for granted and as a birth right of the narcissist.
