But there's a difference between narcissism and just covering for a lack of self-confidence. I'm not psychologically trained, so take this with a grain of salt, but I've met exactly one person that I think was a narcissist. He was a jerk, but mostly because he was utterly baffled by any concept that didn't involve him in the center. It was an attribute completely separate from his confidence. I feel like it is really hard to explain if you haven't met someone like that - I was routinely gobsmacked by his reactions - every human interaction I'd had to date had not prepared me for it. Meanwhile, I have tons of anxiety and often cover it up with false confidence, and our reactions to similar events were dramatically different.
