Have you ever tried going earlier? If you want to do eight hours, try out 4:30AM to 12:30PM sometime. It's hard to stick on it (you've got to be disciplined about going to bed early), but it's great for getting things done while it's still super quiet and peaceful out, and it's awesome having completed the workday at lunchtime.
That's a good schedule for someone who doesn't really want to do things when other people do them. I think it would be like if there was a such thing as being a time-vegan.
Yeah, I periodically try to shift it a bit earlier -- 8 'til 4 is nice.
Not sure I could cope with quite that early though. For one thing, it would destroy my morning go-get-coffee ritual if there were no cafes open when I get up.
