Hm, I used to right ALL THE TIME.
I actually finished a few books...
I just don't do it much anymore.
Huh.
I have a lot of books half-finished too.
There's one that I actually like the plot, but I haven't worked on it lately.
Maybe I should.
Well, I wrote a story when I was like, twelve, called Three Spies. Hahah, it's aweful, now that I look back on it. There were a set of triplets, named Molly, Polly, and Holly, and they had to solve a murder. It was more or less for fun in Creative Writing class with my friends, and completely far fetched. But I'm proud because I actually developed a plot and FINISHED IT. :]
And then for a while I worked on a book called, "Cats Can Fly," but it was kind of a play off Warriors... it had a decent concept though, about mythical cats that earned their wings through good deeds. They were the "light" cats; fairy cats, who fought the "dark" cats; the vampire cats. I got over half way, but never finished.
I was working on a book with the classic plot -- young girl is stupid, falls for wrong guy. Girl gets knocked up. Guy abuses her and leaves. The end. But you know, I was expanding on it and trying to get down into the emotions of the characters... and I love writing dialoge, so there was LOTS of dialoge. I haven't worked on it for nearly six months though.
Though I still love to write, I really don't write anymore and wouldn't pick "author" as my future career choice. (When I was younger, I wanted to be an author, but now I want to go into either education or journalism.)
