When leaders who are used to calling all the shots start working with peers and stakeholders who are as successful, hungry, and confident as they are, they sometimes find themselves at odds. Their previously successful decisive, command-and-control-leadership style is no longer a viable option. And unless they pivot their decision-making style and reposition themselves as open-minded, collaborative leaders, they might be putting their future success on the line. Thus, the overconfident, decisive leader must go through a mindset change.
