One thing that recently clicked for me was making podcasts for my girlfriend / friends / parents on the subject, highlights of books I’ve read. It’s like a virtual book club.
Somehow even though this adds a gigantic amount of burden to reading, it taps into a “productivity” seeking part of my brain that can then create a sense of focus and accomplishment after each book.
Since then reading has been a lot easier and I can usually get to 1 hour per day. Still really underwhelming but it’s way more than I managed to accomplish through sheer force of will in the past
