I like to read more than I like to write. Unfortunately, most of the stories I want to read haven't been written. These stories exist in my head. When a story nags at me, I start searching books in hopes that somehow-- impossibly-- somebody else has done all the work and written it down for me. It would save a lot of time. I could skip all that trouble of putting thousands of words on paper and go straight to basking in: "Oh yes. That's it. That's the story."
Sometimes I can't find a book that scratches that itch. I let the itch fester for a while. If it goes away, fine. If it doesn't...
The old saying is that if you want something done right, you have to do it yourself.
I hope that the stories I want to read and end up writing because I can't find them anywhere else-- I hope they scratch another reader's itch, that someone will open a book I've written and say, "Yes! That's it. That's the story."
