Well, not only did I not getting any new sentences written yesterday, I actually deleted the one I had. It's time for some fresh thinking and a fresh start.
The first sentence of any piece of writing is important, whether it's the first sentence in a chapter, a story, an essay, or a confession. You want to entice the reader and lure them deeper into the chapter, story, essay, or confession until they reach the point of no return. (For great writers, that point is usually right up front. For the rest of us, it varies, with a large number never establishing such a point anywhere at any time.)
So that's my current assignment: Come up with the right opening sentence. Who knows? Maybe I'll come up with one or two more. Just another hundred or two after that, I'll move on to Chapter 20. I'll shoot up a flare when I get to it.
