For the most part I've been reading real estate, business and the occasional political book. At some point, the books I were reading started to feel like a drag. The books I were reading really felt boring, but it was in those categories that I were interested in.
Historical genre would actually be interesting. I've been curious about Roman history recently. I don't know much about it as I would like to.
Do you know about Blinkist? If you're reading about business mgmt and other related topics, they give you 15 minute summaries of the best non-fiction books. It's allowed me to read the important bits from 20 or so books this year so far and choose ones that i want to read in full without committing to buying them. Best Xmas present I got was a year's subscription.
/And no, I don't work for or have any affiliation with blinkist.
I've got a pretty sizeable library of books that I find in old shops that sound really interesting. I havn't read 90% of them, I just kind of collect them and display them in my living room. But one of those few that I actually have read quite a bit of is Meditations by Marcus Aurelius.
It might be a bit archaic, and it is definitely a drag at some points but it is still a great look into stoicism and a review of how the Roman's thought.
What subjects interest you? I haven't had the drive to read fiction in years, and it is something I used to love doing. Most fiction I've read has tended towards fantasy and medieval times. I always wanted to get into serious science fiction, but when I was younger I couldn't conceptualize a lot of it. Now that I'm out of school I should get back into it.
I think historical genres could be a good start.
