All authors seem to have a different method when and how they arrange a time to write. Some write a precise number of hours at a certain time each day. I am not that disciplined, but I can see where this would help a writer to consistently create work. I cannot follow this framework, especially at this time of year. Holidays mean family and friends, visits, long to-do lists, and keeping up at work. Plus, other life events intervene, and these must take precedence.
Besides, I have to have a story sizzling in my mind to stay working on it until it reaches a fairly complete stage. Right now, three are bouncing around in my brain, but my logical and creative viewpoints are arguing about how to make them different, how to make them suspenseful, and how to make them interesting, so the developmental stage is dragging on. Plus, two finished manuscripts are waiting, in need of a final revision. Yet, it seems like I haven't really written in months, and I’m not sure this pre and post-production stuff counts. As of now, actual writing will have to wait until after December 25th, but this time of year is productive in other ways than writing—it does stimulate my imagination.
All this separation from creating manuscripts is useful. As much as fiction writing is all in the mind, the details that make the story connect with readers depend on an author’s interaction and experience with others.
Anyway, I usually write best in summer, so when I'm stuck on details and plot, I can go walk or garden both of which busies my body but allows my mind to zone out and then focus in.
