I loved the article, but the only part that I didn't connect with was the blocking, and probably the goals (not sure if going for the numbers instead of the pleasure of reading something good is ideal long term). I think the author and you shouldn't necessarily be so hard on yourselves to go to these extremes of blocking of these things, usually it works for a while, but it might come back worse when you crack and try it again.
I found myself in a similar situation last year, I felt like I have no time, but I was just scrolling mindlessly on social media whenever there was some off time. As I was reading quite a lot when I was younger, I ended up maybe reading 1-2 books a year, best case scenario. Last summer somehow I wanted to try something else that would help me keep focus or disconnect, maybe for me it worked because of what I started reading. I heard 2-3 years ago on a podcast (Tim Ferris I think) about Ted Chiang and bought one of his collections, but never read it. I got so fascinated with the first book (sort stories, you could just read a story on the go, no huge time investment) and the stories that I ended up reading most all his works, that just hooked me up. A year later, I'm around 2-3 books per month, always try to alternate from fiction to non-fiction, try to mix up and probably the most important part, like in the post, whenever I feel like I don't "vibe" with the book or author, I just stop. Forcing yourself to read a book that you don't like is probably the easiest way of breaking the habit. I even stopped driving to work, the 40 minutes I get per day to read on the train are amazing, it makes me happy if there is some technical issue and the train takes 10-20 minutes longer, more time to read.
