Confidence and a positive self-image are the foundation of a healthy personality. However, too much self-importance and excessive need for admiration might be a problem. Narcissistic personality disorder is seen in those who exaggerate their achievements, talents and remain preoccupied with power or success .They think of themselves to be unique and believe that they deserve special treatment from others. They prefer to associate themselves with people belonging to high social status and often display arrogance. This may tend to cause problems in personal, social and occupational life.
