Yes and that need stems from deep insecurity. Narcissists are insecure, but don’t show it. Their whole superiority act is just that, an act. Very convincing, because it’s what they -want- to be, and when people praise them it’s like a confirmation. They’re addicted to it. That’s why they lash out at anyone who sees through it. When you praise them, they’ll treat you like the best friend/lover they’ve ever had, but once you take away the praise… well they become a nightmare.

See it like this: nobody who is actually self-confident needs to get a constant stream of praise to be happy.
