Their accomplishments will be your signature, the measure of your tenure. If you are confident enough to hire people who are more talented than you are, then you will be known as an audacious leader. If you hire only people who are not as talented as you are, then you will appear to be weak and insecure. And you will ultimately fail. So you decide.
Great leaders are great pols.
Time for a reality check. Leadership is not for the lily-livered. It's not just the casualties that you need to be able to stomach. Dwight Eisenhower didn't become president because of his skills as a general, he became a general because of his skills as a politician. I'm not endorsing playing dirty.
