By the way, if you want to write longer things, I recommend mass production. Sit down and knock out a whole stack of long things, as fast as you can. Do a decent job but don't obsess over details -- fanfic is perfect for this kind of practice. After a while it will just stop seeming long. That's exactly the experience I had with writing classes for the Grey School of Wizardry, which were often around 10,000 words.
Go you!
