“Reading a book about something can be an obstacle to doing it because it gives you the impression that you are doing what you are only thinking about doing. It is tempting to remain in the comfortable theater of our imagination instead of the real world, to fall in love with the idea of becoming a saint and loving God and neighbor instead of doing the actual work, because the idea makes no demands on you. It is like a book on a shelf. But, as Dostoyevsky says, 'love in action is a harsh and dreadful thing compared to love in dreams' (The Brothers Karamazov).”
