As I learn again every day, the art of management is not really about telling people what to do. It's about making people think the way you want, so that they automatically do the right thing without even consulting you about it. A little nudge here, a little nudge there. Politics, I guess, is even more subtle.
And then one day, you notice that big parts of the world are doing exactly what you want without you nudging them first, and it starts to seem a little suspicious. Who, exactly, is the one being managed?
