I'm most productive in the early morning and late evening. The mid-afternoon is my least productive time, perhaps because of lunch or because I live in a sunny area and I'd like to take advantage of the sunshine in the afternoon. I don't mind working 8 hours in a day, but I'd rather do something like the inverse of this person's schedule and work 7 to 11, both AM and PM.
