The sometimes entertaining Rick Gekoski wrote an article for The Guardian about why 'Writing is bad for you', which finished with the hilarious advice from his publisher to stop over-editing:
"That's not writing, that's wanking," he said censoriously. "Finish it, and get on with something else!"Funnily enough, reading romance is also bad for you, but I've known this for years. Won't stop me reading it, though.
