Not professionally, but I do write.
I've written a couple of historical fiction novels (neither published, and neither worth publishing, if I'm honest!), and I'm in the middle of another, rather epic novel (going to be around 400,000 words by the time it's done). I tend to stick to Ancient Greece, because that's the era I'm most comfortable writing in. (Classics student!)
I also write a fair amount of fanfiction. However, very little of it sees the light of day. Just a few pieces here and there that are usually for fairly rare fandoms.
I prefer to write simply for my own enjoyment. I write when the mood takes me, and I always have a notebook on me for those spur of the moment ideas. I'm very sensitive to criticism, which is probably why I don't let many people read my things. I like keeping them just for myself.
Generally though, I prefer to read than to write. I probably read 500,000 words of fanfiction a week, plus a novel or so.
