I think you're essentially talking about something different to what Jeff is. At work, you're there for a set period of time. You have a number of objectives, you do as many as you can in order of priority and convenience, and at the end of the day you go home and do something else. Managing the rest (i.e. getting your car serviced, working on personal projects, learning a new language, going to the gym, meeting up with that old friend, etc etc etc) is harder because it sits in the back of your mind constantly, and can lead to the kind of emotional burnout he mentions.
