I have always admired the Linking Pin theory of management specialist Rensis Likert. It says that in every organization there are leaders who link the lower level to the upper level.

I served 40 years in government, and I'm not looking forward to a position or an assignment. Of course, I have always said if a president asks you to do something, you have to consider it.
