Great leaders build great teams with the expertise to help the organization achieve its vision and, in the process, fulfilled its purpose. In addition, these leaders have the wisdom to give their team the freedom to produce great work because it makes no sense to recruit the best and micromanage their work.
It's counterproductive; it will affect your team's morale and, in the process, create a very dysfunctional place to work. When you have a great group of passionate, inspired, and motivated people eager to make a difference, give them the freedom to work, and create an environment that allows them to become the very best version of themselves.
When leaders recognize that they don't have to be the smartest person in the room, these are the companies that consistently pull off innovative or heroic feats in business because so many of the people who work there are given the freedom to make it happen.
