Was having so much fun with the SEI thread on this topic thought I should Start one for ILE.
I am a Board Game Designer. I love the work that I do, every day I get to work on something new that is going to be a facet of a larger project. The work is truly inexhaustible, and never routine. The people that I work with are mostly INTjs and ENTps, and the art department is staffed with a lot of ISTps, all people that I love spending time with. I also have nearly no schedule.
In the past, I have done half a dozen Sales jobs, but in no way would I ever suggest them as a reasonable career for someone with my type.
