Creativity a disorder?

This morning I've been struck by articles on The Sheer Joy of Writing and Chris Jones's blog. In the first, Mike expresses the frustration that every writer must have felt from time to time. In the second Chris muses that perhaps creativity is a kind of disorder - something I've often thought myslef.

Who'd choose to be a writer? Whether it's novels, screenplays or poetry, the path is long and stony. Where is the audience we imagined as we sat writing?

But sometimes there is no other choice. We're driven by that creative itch. And who would want to do anything but be a writer, anyway? It's the best job in the world.

Yes, maybe creativity is a disorder. But it's not one I'd like to be without.
