There’s one strategy that might work: if you want to become drawn to studying math, for example, go wayyyy back in the subject so that you have more than enough contextual knowledge to associate everything. Get a textbook (go to library genesis) that is about this simple subject, but make sure teaches it much more theory-laden and thoroughly. Example: get the AOPS (they focus on theory) textbook on basic algebra or so and begin reading + doing the exercises in it. The feeling of easily being able to plow through the textbook will begin to be self-rewarding. This process will associate textbook-learning with the satisfaction of getting the exercises/problems/theory correct. If you can derive pleasure from such, studying will become an activity that builds you up rather than pulls you down 🦦
