Exactly. I freely admit that I don't work every minute of every day, but that's because you need to take breaks in order to refocus and mull over what you are working on. You can't cut the time you work in half (which for me often includes evenings and weekends) and expect to get the same amount done. The "extra" work that you add is often work that was unforseen when you started but became necessary as you understood the problem better.
