For a while I thought I just sucked at reading. And to a certain extent I do have trouble (maybe dyslexia, maybe just really bad adhd), but I noticed that when I read older books it’s legitimately a workout compared to books from the last century or so.
This does somewhat include Capital and such, but because I’ve been exposed to a lot of the terminology and because I inherently understand some of the logic, I can get through it.
But for instance I was trying to read Thomas Carlye’s “The French Revolution” and I got through the preface and first two chapters before feeling exhausted. I can’t really describe my issue beyond just having to process each an every sentence like I’m a toddler trying to learn how to read.
Read a page or a paragraph and then I try to summarize what I read in my own words or what it reminds me of, ebooks are ez for me to access to I generally just jot something down in notally on my old fire tablet from 2014, but if I were reading on a more modern device or physical book, a computer I’d use Obsidian or something for notes and the ability to link concepts.
More you read older books easier it gets, I’ve had this problem with some translations of books too, but once I adjust I’ll be ok I figure.
