To manage well requires that you recognize the subtle, but important, differences between people and that you know how to put those differences to work for your organization. Great managers thrive on helping people experience incremental growth. The dynamic creativity of figuring out how to move from the player to the plays is the real genius of a great manager.
Leadership isn’t about that at all. Leadership is about finding the words, stories, and images that bring great clarity to people. And that’s just different from being a good manager. You could have both talents, but good managers don’t necessarily make good leaders.
