Realising my struggles to finish any of my half dozen half done drafts isn't just brain refusing to brain, but my perfectionism kicking in. Everything I've written since I started posting has either been a joke, or something my brain dropped on my lap and fixated on until I clean it up. The main Screaming to the Void parts I've actually finished were all written (if only as messy first passes) in a manic burst in a week or so.
I've got stuff I've wanted to write for months, or years, but haven't tried because I'm not good enough to pull them off to the level I want, and I think I've just elevated my expectations for everything else up there too.
