The one thing I have learned as a CEO is that leadership at various levels is vastly different. When I was leading a function or a business there were certain demands and requirements to be a leader. As you move up the organization the requirements for leading that organization don't grow vertically they grow exponentially.
I remember in the circus learning that the clown was the prince the high prince. I always thought that the high prince was the lion or the magician but the clown is the most important.
