I've discovered that my brain will only accept certain content certain ways. If I'm really into a fun book, then text is perfect. If it's any kind of "literature" or non-fiction, I need to listen to it at the fastest setting my brain can absorb (usually 2x speed) while doing things that would otherwise not be fun (unloading the dishwasher, cleaning, doing laundry, whatever). And I pay attention to my emotional reactions to stuff. If something is too heavy to be fun (or to handle in general), I don't make myself go back to it. I evaluate whether I want to continue. I have more than 1,000 books on my Libby wishlist, so I feel no guilt about moving on to the next thing.
