How many unread books do you own, and how do you feel about that number?

I own about 40 unread books, and I’m hoping to cut down to about 25. I often feel pressured when my TBR is too large, and since I use my library a lot, a small TBR works best for me. That said, I know people who don’t feel similarly pressured by their unread books. Their books are just there as reminders of what they hope to read one day.

So how do you determine what size TBR is right for you? Has that changed over the years?
