Elmore Leonard's Ten Rules of Writing
Probably everyone who has thought of writing crime fiction in the last twenty years has read some Elmore Leonard. Most of us have probably read his "ten rules of writing" at least once.
But for me, it's always a good idea to read them more often. If only because of, "If it sounds like writing, I rewrite it." And all that stuff about keeping the writer invisible, making the story about the characters and letting them tell it.
And only use "said" and never modify it in any way.
Works for me.
