15,440 words later and I've finished the first complete draft on my chapter. I heard positive feedback on my earlier drafts so I'm hoping the rewriting won't be too time-consuming. I've also been running about 3 times a week, and am up to about three miles in about 30 minutes. I've got to start a new book project tomorrow (I'll talk more about it later), but so far I would deem my writing/running program to be a success.
It's funny how once you start concentrating on writing, it becomes easier fairly quickly. It's almost like writing is a muscle that just needs some flexing once in a while, and as soon as you build it up a bit, it's easy to produce some fairly substantial things.
