I wrote a 7000 word, plot focussed, Leverage/Keen Eddie crossover fic in three days, and submitted it, betaed, well within the deadline.
I finally realised that I don't write for fun, but I do have fun writing. I need motivation - a challenge, a deadline, or a complete lack of fic to READ in whatever fandom I happen to be obsessed with (because I'm lazy and I don't need to write it if I can read it).
