I'm currently working on two, one of which is a District 9 fanfic that was actually supposed to be a quirky short story, but now it's a serious chaptered fic. The other one is an original idea that I've been working on for almost a year now. It's actually going to be two books, and my longest story to date.
I feel like writers hype for different things than other people, like when you spend the whole day with writer's block and you finally get a sentence in before bed, that's hype, lol
