Well, the degree I would go for if you could make it fun is Computer Science and Engineering. But I’m not sure if that counts as one category? If I have to pick one, I’d say Computer Science. IT just runs so much of the world these days, and the money is good.
Parkour. I’m getting to the age where hurting myself in the name of fun is more of a chore now.
I’d love to be able to draw.
Math for me, too. I recently made it a personal mission to brush up on the math I hadn’t used since college many years ago. I did the Khan academy thing through high school level and then did some online work through Coursera. I hated it, but I still did it and I’m happy I did. I’d use this unusual gift of yours to make continuing to learn math fun. I have plenty of stick-to-it-tiveness, but I would be miserable doing it on my own.
Organizational and executive function skills. I’m good enough at organizational stuff to be a responsible adult, but, AFAICT, most people are an awful lot better at it than I am. (I have a lot of workarounds to compensate for my innate lousiness at staying focused on boring but necessary tasks.)
I’ve always absolutely HATED dealing with any kind of administrative task. If I could actually enjoy learning how to handle organizing things, maybe I could get better at basic life skills: filing my taxes accurately and promptly, keeping my apartment at least passably tidy, leaving for work on time without being stressed, etc. There’s no guarantee that I’d actually ever become as good as most people are, but maybe I could at least improve a little.
