A writer is very close to their work. What may appear to be an error to the editor, may go unnoticed in the eyes of the author. That is the difference between a writer and an editor. A little tough love here and there from the editor is only to bring out the best in the writer.
If the author is the mother giving birth, I am the midwife making sure that the baby comes into this world safe and sound. Each work of creation is different, and comes into this world through a different passage. Having worked with lots of writers and writing styles, I know that it’s a different experience each time. No two births are ever the same.
