Truck ruminations:
Good writing? I can define or describe that. That's my day job. The best writing? That is trickier.
The best writing carries me forward or backward, flood-like, whatever my inclinations. The best writing surprises me in small or gigantic ways, but always in service to the story, whatever that means. Awakening curiosity or empathy, perhaps forcing such: well, that's the spine, the spoor, the Cain's mark of the very best writing.
Long commute, you know?
