“A book lying idle on a shelf is wasted ammunition. Like money, books must be kept in constant circulation... A book is not only a friend, it makes friends for you. When you have possessed a book with mind and spirit, you are enriched. But when you pass it on you are enriched threefold.” ―
Henry Miller, The Books in My Life
