I allow myself 1 book when I go to the store for a random trip. Going to the bookstore is therapeutic to me, but it's not satisfying without walking out with at least 1 book. I also have this weird thing where I feel guilty walking out of stores empty-handed.

I prefer to buy books so I can support the author and publishing industry. If it's a book I'm not sure about or if I didn't like that author's previous works, I get it from the library or a thrift bookstore. If I don't like a book when I'm done with it, I just gift/donate it. I think it's a really special feeling to be able to own a book and be able to pick it up whenever I want or to display it.
