I probably have 500 books in my house, but I ran bookstores for over 20 years. Friends hate helping me move. I use audio books a lot, but still buy probably 25 books a year. A lot of them have sentimental value- from signings or special events. I haven't read them all, but I have a great plan of diving in when I'm old. Rocking chair, blanket, fireplace, big stack of books. Probably never happen.
