Too many beginning writers seem to think that if they write their material, edit it twice, and send the manuscript through Spellchecker, it's ready to publish.
That's a good start, but not enough.
Perhaps that's obvious, but my wife, Shirley, edited a magazine and curriculum for 20 years. Occasionally, she received submissions with notes that said, "God gave this to me, so you won't have to edit it, you can publish it just as it is."
Not once was the quality of the writing good enough and was usually extremely bad. I didn't know any of the writers, and I never saw their manuscripts, but they were probably individuals who couldn't stand anyone to change their writing. Too bad. None of them got published.
