" As important as it is for all members of a leadership team to commit to being vulnerable, that is not going to happen if the leader of the team, whether that person is the CEO, department head, pastor, or school principal, does not go first. If the team leader is reluctant to acknowledge his or her mistakes or fails to admit to a weakness that is evident to everyone else, there is little hope that other members of the team are going to take that step themselves. In fact, it probably wouldn’t be advisable for them to do so because there is a good chance that their vulnerability would be neither encouraged nor rewarded. "
