The problem is that for most of us those four hours you feel ok about spending doing nothing are the only hours of the day that can be used for appreciably changing your life. For most employees those four hours are all their non-work hours that are truly discretionary and awake. If they don't use those productively they will be employees all their life until they retire. By then they will probably have forgotten what they really wanted to do in life and perhaps be too tired, run down, and or poor to do anything about it if they do remember or discover it.
If you are doing what you really want to do in your "work life" then I could see it. But if you are really doing what you want to do I sort of doubt that their are 4 hours a day that you could do something with that you would blow doing something other than "what you really want to do". We are not talking hobbies, keeping up with literature, exploring interesting things here so much as like sitting in front of the Tube or the equivalent, vegging.
