In my mind, only one inviolable precept exists in terms of being a successful writer: you have to write. The unspoken sub-laws of that one precept are: to write, you must start writing and then finish writing. And then, most likely, start writing all over again because this writing "thing" is one long and endless ride on a really weird (but pretty awesome) carousel. Cue the calliope music.
Chuck WendigSpeed 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 WendigNobody becomes a writer overnight. Well, I'm sure somebody did, but that person's head probably went all asplodey from paroxysms of joy, fear, paranoia, guilt and uncertainty. Celebrities can be born overnight. Writer's can't. Writers are made - forged, really, in a kiln of their own madness and insecurities - over the course of many, many moons. The writer you are when you begin is not the same writer you become.
Chuck WendigYou can feel good about failure. Failure means you did something. You finished the story even if it wasn't what you'd hoped. Failure means you're learning. Growing. Doing.
Chuck WendigWriting is the act of creation. Put words on page. Words to sentences, sentences to paragraphs, paragraphs to 7-book epic fantasy cycles with books so heavy you could choke a hippo. But don't give writing too much power, either. A wizard controls his magic; it doesn't control him. Push aside lofty notions and embrace the workmanlike aesthetic. Hammers above magic wands; nails above eye-of-newt. The magic will return when you're done. The magic is what you did, not what you're doing.
Chuck WendigThe easiest way to separate yourself from the unformed blobby mass of "aspiring" writers is to a) actually write and b) actually finish. That's how easy it is to clamber up the ladder to the second echelon. Write. And finish what you write. That's how you break away from the pack and leave the rest of the sickly herd for the hungry wolves of shame and self-doubt. And for all I know, actual wolves.
Chuck WendigLet someone else take a crack at [your story]. Sometimes, even after time has passed, we're just too close to the thing. You don't want to kill your darlings or, maybe it's the opposite: you just want to kill all of it with cleansing fire. Let someone else confirm or veto your feelings. They'll also bring new questions and complexities to the table, too.
