Book-by-Book or Writing Adventure?

I’m one of those crazy writers who work on more than one project at a time. Some writers understand this, some don’t. For me, it’s a natural pattern I’ve fallen into over the years. I’m not sure how I started writing this way, but now that I’m coming down to the finish line with one project, in the back of my mind I’m thinking about what else to juggle alongside the other story I have going. And yes, I have a ton of editing that’s calling my name relentlessly.
