I can relate to this on one level. I love my job and work crazy hours, but I struggle with burnout regularly, and often need to disengage from work for periods of time in order to recuperate. On the other hand, I am not sure I agree with the 'harmonious passion' argument. I would argue that people with 'harmonious passion' are simply less passionate about their work than the 'obsessives', which allows them to 'turn off the switch' so to speak. As a side note, it is probably fairly difficult if not impossible to objectively measure passion, so I guess it is pretty pointless to debate any of this in the first place.
