I've been writing since I was a little kid. I do fanfic and original stories--lots of short stories in each universe, that go in chronological order and include character development over time, but which are each self-contained plots. I do not comprehend how people can write an actual novel with hundreds of pages!

I've written two or three things that were eventually pretty long, but even so they were (in my mind) more like a series of short stories that happened to take place in quick succession.
I've never put any of them "out there" for people to read. I'm very sensitive to criticism; and I very much enjoy reading my own writing, so really I'm doing it just for me to have stuff to read later. The only other person who reads my stuff is my mom, because she understands she's not supposed to say anything bad about it.

It's just not fair to ask that of other people.
I also write non-fiction in terms of book reviews/reactions, reviews of my own stories, long essays/plans for fictional worlds I want to create, etc.. I used to write in my journal a lot (filled up several of them), but I haven't done that as much for the last few years. Technically I'm a published author for some academic stuff at work, but I don't even count that because in no way is it creative or artful (IMO). I do a lot of proofreading and editing of other people's stuff at work.
Since I'm writing just for myself I don't have deadlines, which I think makes writing enjoyable rather than a chore. If I get stuck on one story I can just put it aside and work on another. I think I have about nine going at the moment; I usually write some every day. It can take discipline to sit down and start writing, and to stay there long enough to accomplish something--I'm easily distracted and I always end up putting my writing off to get other stuff done. If there's anything frustrating about it for me, it's that I wish I had more time to do it.
Also, I wish I had some elves who would magically type up everything that I write by hand--I have a huge backlog of stuff I want to get digitized. Not to threadjack, but does anyone have any suggestions for OCR software that's good with handwriting? It all seems to be geared towards typeset things like newspapers and books.
