MANAGERS DO, LEADERS LISTEN
Sure, leaders do much (much, much) more besides, but the point remains: the best leaders avoid 'too much' doing.
They avoid doing as a displacement activity. They avoid it as a seductive distraction. They've employed others to 'do'. Sure, they'll sometimes muck in and get 'doing' - they'll lead from the front - but they know that too much doing detracts from leading. From listening. From thinking. From strategising. From getting out of the weeds, and planning where to plant the trees. From preventing fires, not fighting them. From doing what leaders are paid to do - lead.
Leadership vis-a-vis management isn't a dichotomy, but there are differences. And, yes, it's an oversimplification, but, in the broadest of terms:
managers do, leaders listen.
