Work Beyond Four Hours a Day

Time has been something tat, i've been obsessed with for most of my career. There's at least one study that shows that working beyond four hours a day is not possible. I need to do other kinds of activity, handle other responsibilities and give my subconscious an opportunity to do some of the work on its own. So can you tell us about what your time ad look ikeAn, and what that im ye, how that on?
