In a Panglossian world, all a writer would have to do is sit down, write a book, send it off to a publisher, and cash royalty checks. This, as you may have noticed, is not a Panglossian world. The old saying, "If you build a better mousetrap, the world will beat a path to your door" regrettably has no basis in reality. If nobody knows you've built it, you and it are just going to sit there looking out the window watching the grass grow. And if nobody knows you've written a book, I wouldn't expect much in the line of royalty checks.
