Having been working on a science fiction novel that covers economics, futures markets, genetic uplift, AI, finance, combat, and orbital mechanics, and having been working on it for 3-5 hours per day for 18 months ( <a href="http://morlockpublishing.com/the-book/" rel="nofollow">http://morlockpublishing.com/the-book/</a> ), I'm somewhat underwhelmed with anything that can be done in three days.<p>I suspect that I spent more than three days on researching lunar geology, minerology, titanium refining, the compresibility of air, etc.<p>Not to mention that my first draft took 9 months, and my revisions have taken 12 months.<p>Some things require iteration and polishing. Writing, IMO, is one of those things.
