It’s easy to be clever, and to disparage corrupt, power-mad politicians with whom you’ll never share a drink or an elevator. But if you truly want to see a powerful, positive change in the world, look directly into the eyes of your neighbor, and say hello as if you have all the time in the world. Because, at that moment, as in every moment, you do. Be common. Be ordinary. Be patient, unsophisticated, and dull. If it is rain you are both tired of, say, “But I love the fresh air, don’t you?” Be positive. Be kind. And yes, be a bit of a fool. Whatever the subject, admit you don’t know. Be willingly along for the ride, and gracious to your fellow-passenger. And then, when you part, let it all go. Let it all grow.
