Just read what you like, at your own pace. I’m probably on the lower end of number of books read, on this sub, (Eight so far this year.) but I read what I’m interested in.

Find the genre(s) you like and read books from them. I use goodreads mainly to track my reading and for a to read list.

I’m currently reading: 'Twelve against the gods" by William Bolitho Ryall

In 1994, I realized I hadn’t read a book since high school and I thought I should read more, so in 1995, I started reading regularly, now (30 years later) I average about 6-8 books a year, I’m very satisfied with myself. Kudos to you for getting back into reading!
