I don't think you have to have a disorder or be destined to never enjoy reading. It takes practice to enjoy a quieter, slower, and less stimulating activity in a world that moves so fast and is filled with sensory distractions.

For people wanting to start reading, I recommend setting aside time on a schedule, shorter times to start, and reading something that really interests you. Save all the "great books" for when you are into a routine, and mix them in with other interesting books.

I think it's helpful to follow the advice that's given to people trying to start meditating. Set time aside regularly, start with short periods, take a few minutes to clear your mind, and keep a notebook nearby to jot down thoughts that you can't set aside.
