Saw a podcast by the guy who played Lex Luthor on Smallville. He pretty much admitted to being a Narcissist who is addicted to attention. Good that he has self-awareness but many seek fame and attention without really understanding why they're doing it. Had a friend like that who was an otherwise wonderful person but her need for attention culminated in her being arrested for faking an attack on herself while hiking. It's a difficult need to control without awareness.
