I try not to edit while drafting a story--and usually fail in the case of short stories and first chapters--but I'm considering following my five-year-old niece's method.
How to write according to Amy...
Write two sentences.
Cross out any misspellings or loose words.
Spend next half-hour drawing pretty and gruesome illustrations.
If you can't find a green crayon, add snot. ("Everyone has green up their noses," she said at my yuck!)
If you can't find a red crayon....use a pink one instead. Phew!
You may want to attempt the above method while writing a steampunk story for the below--though I recommend you don't.
Sean Wallace is looking for stories for The Mammoth Book of Steampunk to be published by Robinson in the UK and Running Press in the US in 2012. Deadline is April 1st, 2011 and the pay rate is five cents a word.
