Excellent point. A while ago I was determined that sleeping less would make me more productive. Then I started actively paying attention to how much time I was wasting one way or another during the day (it wasn't anything obvious like playing WoW or watching too much TV). One of the key things I discovered is the need to have a chunk of undisturbed time so I can really be productive. So I started going to work later in the morning (flexible schedule) and working more at night (guaranteed to have less distractions, even if you wanted to watch TV you can't find anything on).
