With my latest personal writing endeavor, a novel I'm working on, I've made great efforts to go in order, straight from start to finish, because that's something that's been quite hard for me, actually finishing! I'm great at getting a few chapters in, setting things up, but when the task of getting into the plot comes along is where I often falter.
It's taken a while, and without having semi-regular deadlines of submitting work to my writing group, I wouldn't have been able to make it, but I'm actually getting close to the end! Of course, I've changed dozens of details and will need to go back and rewrite and adjust the whole damn thing plenty once I am done, but I'm glad I'm finally reaching the 'endgame' section.
Keep pushing, GrahamRocks, you can do it!
