I don’t normally (wouldn’t presume to) post advice for writers, but when I read this article by Fay Weldon I was struck by her good sense, which comes from her many years of expertise and experience.

I hope you find it entertaining, and maybe informative as well!
Wishing you a happy, productive day.
