One of the hardest things about getting back into reading for me was maintaining my attention. Instant gratification and small dopamine hits from years of youtube and Reddit had burnt my attention span. My solution was to minimize distractions, build a habit, and read something I found interesting. For me, I was recommended the Mistborn series by Brandon Sanderson. I had a slow start. I found book 1 interesting, but felt like I had to force myself to continue for the first ~100 or so pages. It eventually got easier, and I built a ritual.
Listening to music works for me. I now have time set aside before I go to bed, where I use an old iPod and have a cup of tea while reading (with my phone out of reach). This summer I was able to get through “Words of Radiance”, a book from another one of his series, in a week (1000pgs). This took me about 3 years, but I would say it is worth it. The level of satisfaction from finishing a longer story is so much more then the little dopamine hits of a 10 minute YouTube video.
I know the recommendation of “you just have to do it” isn’t that helpful, but it’s the only thing that has really worked for me. The best advice I can give you, is to find the right book for you. I find nonfiction boring, so I avoid it. Arcanum Unbounded by Brandon Sanderson is a collection of short stories that might be a good intro if you like fiction.
