What is your ideal for the most fulfilling job you can think of? I think partly just because you would consider something a job means there is something unfulfilling about it. A completely fulfilling job would likely then be a beloved hobby that you happen to be lucky to get paid for.
Since we’re living in fantasyland anyway, I am going to go off the reservation a bit and just make up a job as my idea of the most fulfilling job. My most fulfilling job would be taking DNA samples of white supremacists and letting them know how many black people they were related to. It would be extra fulfilling if I could tell them they were related to Barack Obama.
