Tips can make someone a better writer but not necessarily a good writer. That's a larger package - a matter of character. Golfing is more than keeping the left arm straight. Every good golfer is a complex engine that runs on ability, ego, determination, discipline, patience, confidence, and other qualities that are self-taught. So it is with writers and all creative artists. If their values are solid their work is likely to be solid.
William ZinsserMy commodity as a writer, whatever I'm writing about, is me. And your commodity is you. Don't alter your voice to fit the subject.

William ZinsserWriters who think THEY are being criticized when only that writing is being criticized are beyond a teacher's reach. Writing can only be learned when a writer coldly separates himself from what he has written and looks at it with the objectivity of a plumber examining a newly piped bathroom to see if he got all the joints tight.
