It's all about who's where on the food chain. When I'm the story editor, I expect my writers to follow my vision. When I'm working for another editor, I'm obliged to follow their vision. ↗
When I'm my own editor, there's very little difference between the first draft and the final. I write what feels right to begin with. I rarely make any major changes. ↗
That's why editors and publishers will never be obsolete: a reader wants someone with taste and authority to point them in the direction of the good stuff, and to keep the awful stuff away from their door. ↗
I try to help people become the best possible editors of their own work, to help them become conscious of the things they do well, of the things they need to look at again, of the wells of material they have not even begun to dip their buckets into. ↗
After I've sent my revised draft to my agent and editor, they suggest more improvement sand again, this revision phase can take anywhere from a few hours to a few months. ↗
