“Basically, I agree with the view that writing novels is an unhealthy type of work. When we set off to write a novel, when we use writing to create a story, like it or not a kind of toxin that lies deep down in all humanity rises to the surface. All writers have to come face-to-face with this toxin and, aware of the danger involved, discover a way to deal with it, because otherwise no creative activity in the real sense can take place. (Please excuse the strange analogy: with a fugu fish, the tastiest part is the portion near the poison- this might be something similar to what I’m getting at.) No matt how you spin it, this isn’t a healthy activity.”
Haruki Murakami, What I Talk About When I Talk About Running, p. 96.
