Do You Have A Story?
And, more importantly, is it worth telling? This is what an article on CNN is asking, Everybody has a story — but is it worth telling?.
While the article is specifically about memoirs, I think it applies to other genres as well. As someone who works with authors on self-help and other how-to non-fiction titles, I always recommend to my clients to do research to see if there will be demand for their book/e-book before they actually write it.
That way if you decide to go ahead with your idea, you will see how realistic your projected numbers are, and how much demand there is in the market for your idea.
