Mine would be creating pen and paper ciphers for my made up secret communication needs.

      • I also did well in school (have my Masters too!) and I got diagnosed with ADHD at around age 30 (I’m female so that made a difference in people’s expectations of how it presents). Totally no need to pathologize a trait or to pursue a diagnosis even if the traits do fir you, but I did just want to chime in that there are plenty of us who managed to defy the trope of “doesn’t apply themselves”.

        For me, I totally do what you do with hobbies! It’s actually why I went into library science - ADHD is my superpower that allows me to be a generalist :P

        I spent last night learning about wood pit clay firing techniques and learning about table saw safety. Why? Idk. I have Ehlers Danlos and I’ve had to give up sewing, spinning, etc, so it’s not like I’m going to be out there making slab tables or digging my own clay but… It’s REALLY fun to imagine and learn all about!

        I love learning about new hobbies and I so rarely find the hobbiest of… Hobbies! Thanks for sharing :)
