I found myself in a similar position a few years ago and had to deliberately choose to read more books. I had gone from someone who read multiple academic books a week (when I was in a humanities grad school program) to someone who struggled to make it all the way through long form articles. I think the mind's natural inclination is to "snack" on things like blog posts, news articles, podcasts, etc, and only commit to a long text when it's engrossing or aligns very well with your natural interests. The trouble is that it can often take a substantial amount of text (much more than a blog post typically contains!) to establish that alignment of interests, especially if the writer is an expert in their field and not a master storyteller. If you are looking to get back into reading books and are having trouble getting over the initial hump, I found that buying a Kindle and Audible version of the same book and switching between formats helps. (Amazon will give you a discount on the audiobook if you already own the ebook and will sync your place between the two.)
