We're all drawn to someone who shows confidence - that is the reason that narcissists are more likely to be promoted or get elected to political office. But on its own, narcissism is dangerous. It tends to promote overconfidence and it dismisses the criticism.

The humble narcissist believes they can do extraordinary things but know they always have something to learn.

Narcissists believe they're unique and superior, while humble leaders know they're flawed. 

Performance humility is admitting that you fall short and make mistakes.

When we focus on hiring people who fit the culture, we end up with people who are similar to us. That prevents the diversity of thought and background.
