Well, I think there's some factors. I can focus really easily into something and get completely absorbed in it. That helps immensely. There's a huge part of your mind that only activates when you're completely shutdown from outer stimuli and completely focused into something. That part of your mind is hundreds of times more powerful and efficient than your normally used part. If I can't focus like that my productivity drops drastically. And that can happen any time for a variety of reasons.
