They use the correct words, but they rarely mean them. They usually mean, "Tell me how wonderfully I write." Until someone points out their weaknesses, they don't see them.
That's been true for me and I've become a better writer for having been edited. Although that's true, I wrote for several years before I could look at an edited manuscript and detach myself emotionally.
These days, my wife reads everything of mine before it goes out and sometimes my assistant, Twila, peeks at my work. Through the years I've learned to be thankful for Shirley's excellent eye. I'm embarrassed when a bad sentence sneaks past me; I'm grateful when she asks, "Can you clarify that point?" Or Twila will ask, "Did you leave out a few words?"
Serious writers can find help and they'll accept help because they're serious. They can take on-line courses or correspondence courses; they can attend conferences; they can read books on writing. We have such an abundance of resources that it leaves us no excuses for not improving our writing. I believe that writers learn best by being part of an editing group as an ongoing, learning experience.
Serious writers continue to learn
because they're serious.
