I have a hard time throwing away all my books. I have never thrown any away yet, but I have never needed to. Especially since my reading process is quite surprising. When I buy a book, I never read it entirely. So, all around the house, I have several books started. When I walk into a room, sometimes I read a page or two of a book.
For the most part, they are not novels. Rather reflection books. I think therefore that my system has been built around that, I take a concept and I let my brain meditate on it.
Yes! We used to do that too. Concept books are lovely.
