There are two kinds of editors, those who correct your copy and those who say it's wonderful.
Sentiment: POSITIVE
I have great editors, and I always have. Somehow, great editors ask the right questions or pose things to you that get you to write better. It's a dance between you, your characters, and your editor.
Truth is, every writer has to be a good editor, and you have to edit yourself. It's a skill every writer has to acquire.
If you're not in the hands of an expert editor, you really can go wrong in a lot of different ways.
When you're editing, you want to be the perfect appreciator, not another writer.
I know that many authors say editors don't edit anymore, but that's not been true in my experience.
One should fight like the devil the temptation to think well of editors. They are all, without exception - at least some of the time, incompetent or crazy.
I have been blessed to have the same editor and work for a great publishing house.
A good editor understands what you're talking and writing about and doesn't meddle too much.
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.
Writers have to put up with this editor thing; it is ageless and eternal and wrong.
