Me with nothing to do+active rps=me in front of a computer rping the entire day. The embarrassing moment when you realize you've posted twenty times in the same rp in one day? Done that.
word count encourages me? I'd do nothing otherwise. I respond well to deadlines. I've written as much as 3k in a single day mostly in rps. Right now, I'm relying entirely on rps for my words because I have nothing to work on.
