I think training your instinct comes from writing and reading. There's no big secret. And reading slush helps, as well; I'd recommend everyone edit a literary magazine at some point. It's time-consuming, but there's a lot to learn from other writers who are also learning. The patterns (twelve stories about whales in this batch?) are also interesting.
Mary J. MillerIt's something that's difficult to explain but I think all writers work this way to some extent, whether we're aware of it or not. For me, writing has little to do with thinking. I don't want to control the narrative. I listen to the rhythm of the words and dialogue and try to give the characters the space in which to say and do what they want without intervening too much.
Mary J. MillerTo be quite honest, along with thinking and such when it comes to writing, I'm not into words like "theory." I'm a PhD dropout. No matter how many twenty-five-page papers I wrote, I never felt like I was saying much. I didn't feel like the writer of the book, whose work I was analyzing, would have been impressed. It didn't matter how much time or effort I put in.
Mary J. MillerThere were definitely scenes I struggled with more than others: the car accident and the thunderstorm are two that come to mind. It's difficult to write about a thunderstorm. There are only so many ways to describe it and our vocabulary is so limited. And the car accident scene required a tense, manic quality that had to be conveyed in the language, as well as the character's dialogue and actions. I was editing these scenes long after I thought I was finished with them.
Mary J. MillerI've learned a lot about language from reading slush. You can immediately tell if a writer is in control of the narrative. This writer will avoid using too many words like "possibly," "probably," "maybe," "perhaps," etc. He/she will avoid using clichรฉs, as well as a lot of metaphors, and won't take four sentences to say what they could in one (or write a great sentence and follow it up with a bunch of stuff that just weakens it).
Mary J. MillerThere's definitely a magical quality to writing that can't be explained. I can write something I love in two days, or I can work on a story every day for months and it never comes together.
Mary J. MillerIt's definitely about the rhythm of the words and how they sound together, writing one sentence and then another and another and cutting something immediately if it doesn't feel true. I come from a family of musicians and - while I have no musical abilities of my own - I think I inherited a good ear.
