I think the post did make a classification mistake there. I'm not sure exactly what is meant by professional, but there are a lot of jobs people can find fulfilling that are not in the classic defintion of "professional", like park ranger or dancer. And there are a lot of professionals who don't like their job and do it just to get a paycheck. I think otherwise the post does raise a very good point about the importance of having more to your life than just work.
