I still do that myself I’ll read a whole page and then realize I have zoned out the entire time and remember nothing. Usually that happens when I’m not as invested in the material. I’m current reading the wheel of times series and am enjoying it. However it has it’s boring or just overly detailed areas that I find myself zoning out more in.
I get that it is honestly hard to read stuff you just don’t connect with or find interesting on some level. I absolutely loved the odyssey and huck finn. I can completely understand people not getting on board with Shakespeare especially when you’re younger.
I’ve definitely gone back in red some of the really popular books back when I was in high school because I can appreciate them more now. However, I still read a ton of fantasy novels and stuff like that which I find more interesting then most things I read back then.
