Some people are passionate about always doing the best they can, and they get a great deal of satisfaction from it. I love being excellent at what I do.
I don’t have a wife or kids. My jobs are a huge part of my identity. Heck - my night job teaching is something I do because I want to do it, not for the little bit of extra money.
But I also know that I’m weird. Most people just want to do their job and go home to their families, and that’s great. They’re doing the job, so they should be compensated every bit as much as the people like me who are devoted to their work.
