What works for you is going to be different for what works for others. For me I listen to audiobooks while doing other work that I can split my focus doing. Long drives, for example, are perfect for me to listen to books. On the other hand, if I take ADHD meds I can’t really listen to books while I work because my focus on meds doesn’t let me really split my attention. I definitely can’t listen to “heady” works like theory while working because I won’t absorb it properly. Some people can’t really split their attention while doing something like driving either, it’s really going to come down to a lot of factors.

I’ve often found that reading physically is something that I have to build a habit for. If there’s a book I want to read I may put it off for ages until I finally lay down before bed and dedicate an hour or two to reading, and generally (unless I really don’t enjoy reading said book) that inertia will carry over into subsequent days. So you may need to self examine and think about how you focus personally and work with that.
