Narcissists cut a wide, swashbuckling figure through the world. The most benign type may be the charismatic leader with an excess of charm, whose only vice may be an inflated amour-propre. In stark contrast are individuals with narcissistic personality disorder, whose grandiosity soars to such heights that they are easily angered when they don't receive the attention and admiration that they consider their birthright. Bona fide narcissists may also have a tendency to disregard other people's feelings and take advantage of others to get what they want.
As with many characteristics, narcissism can be viewed as a spectrum: Some people are lower on the trait and others higher, with many landing in the middle. Out-and-out narcissists exhibit the highest levels of self-flattery.
