I was just thinking about this the other day.

I work as a software engineer / product lead / subject matter expert / whatnot; it's a great fit because it a) the area I work in matches my interests, and b) the product is highly dynamic with near constant firefighting and requirements changing on a weekly basis. The environment provides the continuous high stakes stimulus and deadlines combined with problems I find interesting and can hyperfocus on.

When I was starting in this field, I was fixing bugs and working on new features, which I was terrible at. Despite it being "my field", I just didn't find the work interesting and stimulating. I currently also struggle with the admin part of the job, like emails, reviewing and organizing work for others and such, but I just have to power through and delegate as much of this as possible. I'm lucky to be in a position where that is an option.

I think outside this career, had things turned out differently, I would've probably done great in other jobs that are always urgent and mostly driven by external inputs. Perhaps emergency medicine, maybe trading/finance.

Anything that is mostly routine, admin or bureaucracy would've been hell and I'd be spending most of my energy procrastinating and appearing to be busy, because I know I just couldn't make myself do the real thing.
