I see your collective sanity and raise you my crazy. I've decided to actively pursue the polyphasic sleep schedule (Uberman, to be specific) in order to test out two different things at once. The first is a test to see if polyphasic sleep increases or decreases memory retention... the second is to see if 10,000 hours is really the target goal to become a professional at a field.
In the next year I'm going to be polyphasic and attempting to incrementally increase the amount of guitar practice I do every day from somewhere around 12 hours (which is where I got in my test run of polyphasic sleep) to a whopping 20 hours of practice a day. At 20 hours a day I'll have practiced 7,300 hours in a year (assuming it goes off without a hitch, which of course it won't). But I'm going to try anyway.
