I think it takes more work than a lot of people are willing to put in, sadly. When I was taking nothing but lit classes (it was my major) I would spend 6 to 8 hours of my day reading things I usually didn't feel like reading. I got used to it but when I would tell that to people they would look at me like I was crazy to spend so much time doing one thing. The trick is to make yourself do it until it feels normal to pay attention.

The other learned superpower I can think of would be cold reading but its really only useful if you are trying to con someone into thinking you have a way cooler superpower lol.
