Excellent piece, Matt. I agree perfectly with everything you've said, and I see how I can apply them. However, the only exception I dare make is for people who are traditional 'night owls'. I know of a few great writers who were naturally very productive at night. Because of their exertions at night, they woke up a little later than most people did. But yes, the other habits listed also played a part in their success, not just the time of rising.
