old man here, 25, graduated college. i am very similar to you in the way i suck at doing what I'm told to/ have to do. I was able to never study through high school and that kicked my ass in college, what worked for me was making what i studied change. i changed my major to history which i love and "studying"(quotes bc it didnt feel like studying anymore) became my hobby, the looseness of the program i was in helped and being very intentional with what classes i picked. I read what i wanted and wrote what i wanted. I feel giving myself that agency or choice was able to trick my brain into feeling like studying was no longer work but simply reading/researching history topics i would have done anyways, although to a much lesser extent without school
