A leaders number 1 goal is to be the least competent person in the room.
A good leader hires people who are more qualified than themselves, and they provide a path for their existing people to grow and move forward.
They give people the room, and the encouragement, to outshine their boss.
A good leader's goal is to become obsolete and to know when their job is done.
They know when to go looking for their next team to build.
