I have lots of mostly useless talents because they're only good for very specific things...
I can wiggle my ears, flare my nostrils and unhinge my jaw. They're fun party tricks to gross out new friends.
I can paint and draw both digitally and physically. I've even published illustrations in the past (locally but hey, it's still published) as well as commission work for people online.
I can code in Pascal, php, C+, a very specific PLC language, and know how to program those robotic arms they use in machine factories. I designed a very basic pet sim back before web hosters got super strict with their hosting. I've also made a handheld Simon Says game.
I can do three digit multiplication in my head about as fast as someone can punch it into a calculator.
I can touch type 120+ wpm with a qwerty keyboard. This also means I can copy type most things faster than I can highlight and hit ctrl+C and ctrl+V. It also means that my writing sounds like a literal machine gun going off when I type.
