Narcissism is the personality trait that features an exaggerated sense of the person's own importance and abilities. People with this trait believe themselves to be uniquely gifted and commonly engage in fantasies of fabulous success, power, or fame. Arrogant and egotistical, narcissistics are often snobs, defining themselves by their ability to associate with (or purchase the services of) the "best" people. They expect special treatment and concessions from others. Paradoxically, these individuals are generally insecure and have low self-esteem. They require considerable admiration from others and find it difficult to cope with criticism.
