For me it's always been reading. I can read fine when Im interested in something, but if it's something boring, I literally cannot force myself to read something. Even if I do just overcome the absolute internal refusal, I will retain zero information, and have to read the same page repeatedly. I fucked off so many book reports, and just wish the internet was around when I was in school.
Even to this day, I'm sure it's a touch of adhd, I can't force myself to read shit that doesn't spike my interest. Give me a video, or movie, or another medium, or fucketh off.
Have been digging audio books on road trips lately. Packing for Mars was cool.
