ThisRecording.com has an on-going four-part series filled with useful advice for the writing process from numerous famous authors such as Kurt Vonnegut Jr., Thomas Pynchon, Vladimir Nabokov, and Toni Morrison. There is much to be gleaned here about crafting poetry, short stories, or fiction. Here are two excerpts:
Sometimes I would sit at the machine for hours without writing a line. Fired by an idea, often an irrelevant one, my thoughts would come too fast to be transcribed. I would be dragged along at a gallop, like a stricken warrior tied to his chariot.
My method is one of continuous revision. While writing a long novel, every day I loop back to earlier sections to rewrite, in order to maintain a consistent, fluid voice. When I write the final two or three chapters of a novel, I write them simultaneously with the rewriting of the opening, so that, ideally at least, the novel is like a river uniformly flowing, each passage concurrent with all the others.
-- Joyce Carol Oates
