The over inflated ego is actually projection of insecurity. A lot of times the best answer is not going to come from your own fucking noggin. When I get someone in a situation like that, I put them in charge of something. And then they'll do it successfully and their confidence will be increased. Urge people who have big egos but maybe not so much that it's not correctable.
A special throwback episode ft. Jocko Willink. In the episode, we talk about the opposing qualities that leaders need to develop, tactics for dealing with lack of confidence and other challenges leaders face with any team on the planet. This is as thorough an education on leadership as you’re going to get in less than 90 minutes. If you’re wanting to find out more on leadership, be sure to check out Jocko’s latest book, “Leadership Strategy and Tactics: Field Manual.”
