" Once you have piled your books, take them in your hand one by one and decide whether you want to keep or discard each one. The criterion is, of course, whether or not it gives you a thrill of pleasure when you touch it. Remember, I said when you touch it. Make sure you don’t start reading it. Reading clouds your judgment. Instead of asking yourself what you feel, you’ll start asking whether you need that book or not. Imagine what it would be like to have a bookshelf filled only with books that you really love. Isn’t that image spellbinding? For someone who loves books, what greater happiness could there be? "
