Maybe we should just stop focusing on how many hours we work, and concentrate on what we want to do and on whether we've achieved it. I feel that not focusing on the hours just works better. One day I feel tired, and I'm not advancing? I go home. The next day I feel energized, and I want to keep working? I can work 12 hours straight. No limits, nobody tells me what I can or I cannot do, and when I should do it. Of course, we may need a bit of tracking hours in order to understand what we're doing and how we're spending our time, but we can use a more coarse granularity (like "half days").
