Why aren’t your books selling? It could be that your book is too similar to books that are already out there. Lots of authors find themselves telling the same stories over and over, and I maintain that anything that Shakespeare didn't write, the Greeks already wrote. To that end, lots of Shakespeare stuff looks like the Greek playwrights. So if you’re looking for a new idea anyway, look around the book market. And ask yourself this question: what hasn’t been written yet?
A Tale of Two Writers
So, you probably don’t think of Julia Child as a writer. If you think about her at all, it’s most likely you’re thinking of Dan Aykroyd. That’s what I think about: a tall woman with a high-pitched voice, showing me how to cook a turkey. But Julia Child was also an incredibly successful writer, and not just a world-famous chef. She noticed a book that didn't exist, and she wrote it. That’s pretty much what all authors want to do, and she succeeded at it.
