This most practical for nano, but there is something to be said for even noveling with a far more forgiving deadline, and no word limits.
Ration your words or scenes.
It’s easy to get lost in the overall scope of the novel. I’m at 40K and I’m still overwhelmed at the thought that the end is near, and my plot is moving along like a turtle. Rationing words, saying you’ll only worry about say, 3 or 4K a day makes the goal more manageable, and leaves you only responsible for 3,000 words. It also removies feelings that by some kind of miracle I have to get that 30K written by tonight OR ELSE.
Or I could say, okay, I’m only going to worry about getting all this business about how all the different spirits relate and work with each other (or don’t) and how they operate among humans and other living creatures, and then we’ll call it a day. And that can easily give you almost 3K right there. That is, if you don’t stop to give them fancy names in another language. It has a way of slowing down writing, and dangerously distracting, but it’s fun.
It might also be time to switch writing modes, and who knows what that means: getting off the computer (or for some of the the more old school typists, you’re Typewriter) for some intimate time with a pen and notepad, writing in the morning instead of the evening (or vice versa), or even writing while slurping a fruit smoothie instead of that bottle of Mountain Dew which, God knows, isn’t healthy for you anyways, or exchanging that stash of Chocolate for a crunchy granola bar (although, I must confess, I’m sorely tempted to bring out that bag of swedish fish I got and see if I can’t get any more awesome word count action like the last time I wrote and ate).
