It hurt to have him slash sentences I had written and rewritten ten times. But he caught things I hadn't seen. Intellectually, I knew he critiqued my material; emotionally, I felt he critiqued me.
Although I've now published more than 100 books, I still don't like it when an editor rips apart my prose. No matter how hard I try, editors find ways to tweak sentences or delete words. Unless you self-publish, someone will always edit behind you.
Being edited is part of the getting-published process.
If you can't accept editorial changes,
don't write for publication.
