What’s your current hyperfixation? Mine is history

What is yours? Tell me all about yours! When’d it start, how long has it been? What have you learned? Did it cost you any ADHD tax? :)

Okay, this bottom part is just gibberish because this sub requires a lot of characters, which I’m sure I met, but keeps asking for more for some reason. So just ignore this part :)

Edit: I’m trying to reply to everyone Dx it’ll take me some time! I got overwhelmed with the responses!
