As a writer, if I have one complaint about editors, it's that they don't give a piece a chance (apologies to John Lennon). They don't read far enough, or they make snap judgments based on only a few paragraphs. They don't follow through and find out (cough, cough, ahem) what a great writer I am.
As an editor, if I have one complaint about writers, it's that they fumble their openings. They feel they have to explain everything, or they try to be too sophisticated, too cute, too whatever of one thing or not enough of something else. In short, in trying so hard to get it right, they get it wrong.
I know, 'cause I get it wrong all the time.
The only way to keep my sanity and still perform my duties as both writer and editor is to understand that the two jobs are not the same, but they don't need to be at odds with one another. After all, isn't the goal to produce strong writing and therefore good stories?
It's a Jekyll and Hyde world, and I'm just a wanderer here.
