Honestly the more I read I find this attitude to be exactly the opposite of how I feel. When I'm trying to read a book, I need to be immersed in it. I don't want it to be a mindless distraction, because I am putting 100% of my focus into driving, or cleaning, or yard work. Driving perhaps is the one that gets me the most, I can't appreciate fiction at all while driving because I have to keep my imagination in check so I don't kill someone veering off into space. And non-fiction, well, I have never been able to digest hard topics if I'm distracted by wistful activities.
