when deciding which books to keep, forget about whether you think you’ll read it again or whether you’ve mastered what’s inside. Instead, take each book in your hand and decide whether it moves you or not. Keep only those books that will make you happy just to see them on your shelves, the ones that you really love. That includes this book, too. If you don’t feel any joy when you hold it in your hand, I would rather you discard it.
