I discovered once again that the audiobook can be a terrible format for certain kinds of nonfiction works.
I tried Principles for Dealing with the Changing World Order: Why Nations Succeed and Fail by Ray Dalio. I used it for a return commute, said after I got home 25 minutes in, "Okay yep this sounds like it'll be full of tasty information about my immediate future and give me the nuance and language I need to more adequately talk about our dying planet/entire life system!" You know, where I stopped seemed to be the end of an introduction, presumably the prose would start to get some flavor shortly.
But no, the whole thing is very clearly meant to be read. HOO BOY. Lots of "as shown on Figure A-5..." and "as we see how the shift evolves from curve D to D1..." I hate that I can't focus sufficiently on it to visualize the context and ideas with my own brain. I'm willing; I want to be the driest person I know!
But no. I lay down after I got home, kept the audiobook going, fell asleep after 5 minutes. Woke up and I was 2/3rds of the way through the book and everything sounded exactly the same as when I fell asleep!
I'll have to try Mr. Dalio on paper. Guess it's high time I properly pick up a book again, anyway.
