I mean, there's not a lot to do with a self-imposed deadline or even much advice to give without sounding like Nike or Shia Laboeuf; "Just do it." Honestly, I'd say just sorta write whatever, as long as it meets the length needed, fits the style guide, and more or less stays on topic. If it's rambly and nonsensical, it really doesn't matter. I've seen so many dissertations that drone on or just read like the ravings of a madman for a chapter or two, it's wild.
