Adulting generally sucks, but one of the main things that doesn’t is that nobody’s asking for a book report later. Read what you like, in the manner and style that you like, or however you are best able to.

Personally, I usually have several books going at a time, and it’s rare that one captures my interest enough to read multiple chapters straight through. I also don’t have the leisure time I would if I were retired or wealthy, so I tend to read less than I wish I could, but I’d rather take a couple of months to get through a good book than just… not.
