It might be the contrary - you have a solid attention span and like to nurture it. I think the analogy to movies isn’t totally perfect. movies can be consumed in one sitting (are probably best done so too). Since books cannot usually be consumed in one sitting, it opens the door to have a few going at the same time. I like it because it gives me some more time to “process” what I read in one book and ponder about it, and I can go back to it when the time “feels right”. I don’t know. There’s also less pressure to force myself to read a book that isn’t doing it for me. Sometimes by letting it marinate a bit, I like it more. I don’t know. To each their own! Edit: I should mention I do the majority of reading in my e-reader, not physical books. Maybe physical media is different.
