Is it possible for a person know they suffer from narcissism?

Narcissism: When others confront them with their arrogance and lack of empathy, they start to gain understanding and some insight.

Narcissism: Many can, yes. The hallmark of a narcissist is an immense ego, grandiosity, and self-importance, as well as being entitled, and a tendency to use and objectify others as well as thinking of people in all-good or all-bad terms instead of shades of gray. The core of a narcissist is profound insecurity. They are very difficult to treat, usually defending against profound narcissistic injury.
