I did this in the last couple years, I used an 'atomic habits' kinda approach. I put a book on the back of the toilet and pledged to read 1 page before looking at my phone. It worked out nicely, I've read a bunch of books over the last year or so after kicking it off in that way.

I am also not a lifelong reader, I didn't start reading until college. My girlfriend read a ton and the first Lord of the Rings movie was about to come out, I got caught up in the excitement and read all the books. Ever since then, I've read pretty steadily. Interesting though, it wasn't social media or anything that slowed my reading to a trickle, it was audiobooks. I freakin love them when the narrator is good. Anyway, that's how I got back to reading and now I haven't listened to an audiobook in a while. :)
