“It is this experience of seeing something one has written come alive—literally, not metaphorically, a character or scene daemonically entering the world by its own strange power, so that the writer feels not the creator but only the instrument, or conjurer, the priest who stumbled onto the magic spell—it is this experience of tapping some magic source that makes the writer an addict, willing to give up almost anything for his art, and makes him, if he fails, such a miserable human being.”
