It'd be nice to enjoy your job and have some sense of fulfillment in it. Probably the only thing that fits the bill for me was when I used to play music professionally. That was fun, despite being hard work. In live situations audiences seemed to enjoy themselves and in recording situations the artists were usually grateful. That was nice. But I never did that full time. I teach a couple classes at my church and some have said they get a lot out of it. That's rewarding, but it's not a job.
I used to work for oil companies doing...it doesn't matter, it's so boring I can't stand to describe it. Good money but nobody missed me when I left the industry and all day you work knowing you don't matter much, if you weren't there, somebody else would just fill the spot and do the same thing. Lately I've been working for my wife's clinic, where she and the other provider assure me that my job matters, but judging by what they pay me, it doesn't. I shuffle some papers around and know that an adequately competent 6th-grader could do my job.
I went back to school for a MS in Data Science. Should finish next Spring, and hopefully get a job that pays more. I reckon I still won't have much job satisfaction. I'll write some code to manipulate some numbers, maybe query a database, feed some other numbers to a machine-learning algorithm and oh god it's so boring I can't even type about it anymore. In the end I'll know it still doesn't matter. If I didn't do the job, a company would or wouldn't make some decision that probably doesn't matter much, and anyway, if I didn't do it, somebody else just like me would. All in all, I'm just another brick in the wall.
