I believe books should be read and that they should be acquired with the intent to read. What one does with them beyond that is ultimately up to them. After a while, books that take up shelf space and that have not been held or thumbed-through relatively recently should be set free.
I believe books should be read but that if one loses interest or they intuit that they have received what they need from said book (assuming it’s not a narrative whose conclusion one must experience), they should have no qualms about laying it aside either permanently or until they are ready to wrap their mind around it.
I believe books can be judged by their covers. To see that this is so requires at least some interest or knowledge of design, type, font, etc.
I believe one should look up any and every word they don’t know.
