I'm not afraid of working in industry, I just don't want to.

Why shouldn't something you do for 40 hours a week not be considered what you're doing with your life? I have a strong inkling that many of the people I've called my supervisors over the years have considered it a (very significant) perk that they get paid to do what they love most, and the pay isn't like what doctors and engineers get anyway - nobody goes into the lab for the money.

Microbiologists come to mind. I was at Woods Hole in the summer of 2012. My roommate got on my nerves sometimes when she got up in the middle of the night and left the room, and when I finally asked her what was going on, she said she had to incubate bacteria. Microbiologists work the weirdest hours but I don't think they would have stayed in this subfield if they didn't positively love working with the little buggers.

Paying the bills is obviously a necessary part of life, but I'd rather that be a side effect of my job rather than the purpose.

Screw a job, I've got a vocation and a calling. Which happens to pay the bills.
