I have noticed that people who do real work, are the ones neither “love” their job (and convincing themselves they love it) or hate their job (no shit.) They are the ones who show up, do what needs to be done, they do what the boss tells them to (about the job of course,) and then they’re done.
Maybe the people who are bad at their work compensate their incompetence by loving or hating their job, if that makes sense.
