Some level of narcissism is healthy – we all have to have sufficient self regard and self love to manage confidently and move ahead in uncertain times. Too much though – and this is sadly common with business leaders- can destroy a team and negate the power one gets from leveraging individual skills collectively. If you’re a business leader, it is especially important that you identify your own narcissism and manage it appropriately. The stronger a leader’s narcissism is, the more it needs to be managed, but the less likely she will recognize it. Sad but true.
