Something not STEM. I've bought into the whole STEM circlejerk for a while now, and even went so far to condemn anything not STEM. My opinion changed when I took World History, and I really enjoyed it. I've always been curious about philosophy, but I never actually took the time to try and pick it up. I think that's just a matter of "I don't know what to expect." I'd also like to get into art. I've tried writing or drawing before, but I almost always end up throwing my pen or pencil down in frustration because it's not perfect or because it reads awkwardly. I've always gotten a As and Bs in English, but that's mainly analytical writing and it always feels like I'm just pulling things out my ass. Finally, functional programming. Since that's the new trend nowadays in the programming community.
