Speed is not an indicator of quality in terms of fiction. That's true of one's relative slowness or swiftness - taking 10 years to write a book or taking 10 days to write a book (or a comic or a film or an angry postcard) guarantees nothing in terms of how good or how bad that story is.
Chuck WendigWrite like you write, like you can't help but write, and your voice will become yours and yours alone. It'll take time but it'll happen as long as you let it. Own your voice, for your voice is your own. Once you know where your voice lives, you no longer have to worry so much about being derivative.
Chuck WendigRead your work out loud. Don't give me that look. Read your work aloud. Don't argue. Don't fight. It will help. I promise. I promise. I guarantee it. If you find it didn't help you, lemme know. I will let you Taser me in the face. And by "me," I mean, some other guy who will be my stand-in. Probably some real estate agent or tollbooth attendant.
Chuck WendigQuestion the Chestnuts. Chestnuts: the new name for boobs? No. NO. Why would you even say that? Get your mind out of the gutter. No, by "chestnuts" I mean, "those old pieces of writing advice that you hear as common refrain." 'Write what you know.' 'Adverbs give Baby Jesus hemorrhoids.' 'If you write a prologue, an orphan loses his sight.' All the "old saws" need to be put on the chopping block.
