Narcissism: Symptoms and Signs

Other signs include:

• A sense of self-importance, exaggerating their achievements and talents
• A preoccupation with fantasies of success, power, or brilliance
• A belief that they’re more special or unique than others and should only associate with other high-status people
• Envy of others or the belief that others are envious of them
• Insisting they have the best of everything
• Feeling they deserve privileges and special treatment

“Narcissism is extreme self-involvement to the degree that it makes a person ignore the needs of those around them. While everyone may show occasional narcissistic behavior, true narcissists frequently disregard others or their feelings. They also do not understand the effect that their behavior has on other people.”
