That's not my title, that John Scalzi's. Scalzi is a science fiction writer. I've never read his work. I found his Utterly Useless Writing Advice on his blog while surfing.
I haven't actually finished reading his advice. It's a long post. Also, I've already made several choices contradictory to his advice. Still, it's worth taking a look at if you hope to write for money... one day.
