Professor Zueblin is right when he says that thinking is the hardest work many people ever have to do, and they don't like to do any more of it than they can help. They look for a royal road through some short cut in the form of a clever scheme or stunt, which they call the obvious thing to do; but calling it doesn't make it so. They don't gather all the facts and then analyze them before deciding what really is the obvious thing.
