Leadership Is Like Medicine
The practice of leadership, like the practice of medicine, involves two core processes: diagnosis first and then action. And those two processes unfold in two dimensions: toward the organizational or social system you are operating in and toward yourself. That is, you diagnose what is happening in your organization or community and take action to address the problems you have identified. But to lead effectively, you also have to examine and take action toward yourself in the context of the challenge.
