(In my world, a short story is roughly 1500 words long.) I normally spend as long as 20 hours writing the rough draft (4-5 hours a day). Then I would go back and reread it and end up spending about 5 hours changing things around. I don't really use my time efficiently because my computer is connected to the Internet and I'm always looking stuff up online even though I don't really have to, but I would say it takes me about 25 hours to write a short story from scratch. And you?
