I was fortunate enough that I could take a week away from home to write, write, write on my book manuscript this summer. I rented a small and simple cabin in Nyvik, about 45 minutes south of Umeå, right on the coast, loaded up with food, books, coffee, chocolate, and one good bottle of beer for each night, and had my wife drive me down there.
Such writing binges are certainly not sustainable in the long run, as I was quite exhausted when I came back home, but I made some serious progress on the book. The problem so far is that I have done tons of writing on the cabin project, but most of it is not book-shaped. So I have spent much time structuring what I have, rewriting it for style and content, and generally stitching it together. Scrivener was very helpful at this stage, making it very easy to see the overall structure and to move things around.
In order to finish the book this fall, I need to continue with a regular writing schedule, taking one bit at a time. I will launch an online writing group using the pomodoro technique over at Ant, Spider, Bee when the semester starts, hopefully that will keep me on track!
