The world is full of people who know more than we do. They are wiser, smarter, more experienced. If only we listened to such folk we would never put a foot wrong. Success, to say nothing of a sense of great well being and righteousness, would be our only experience. So where are these great gurus to be found? They are everywhere, offering advice we do not want when we do not need it. And when we do? Magically, they vanish.
