An editor is an accomplice, looking in from the outside. That objective view is essential. We don't write in a vacuum, and we don't publish in a vacuum.
I gave up writing for seven years (very biblical) and picked it up again, still clueless and still seeking the exotic, when I was twenty-one.
Invite characters of surprising and moral character, or at least those who grapple with what is right or those who make decisions that shock.
For me, when I 'discover' a story, there is a feeling of buoyancy and clarity, perhaps similar to early morning out on a prairie highway, when darkness lifts and reveals the outline of farmhouses and copses of trees in the distance.
When I get moved to write a story, I don't question the story. I dive right in, and I try to ignore the voices that are chattering away at me: 'You can't do that', 'You shouldn't do that'. I just sort of leap and take a chance and go for it.
