"the contents of the noise in your head"
More on words from an odd little book called A Few Short Sentences About Writing. Verlyn Klinkenborg suggests:
Write these things down–the contents of the noise in your head as you write. You can't revise or discard what you don't consciously recognize.
Mary Oliver wrote in her book about the importance of revision. Her poems, should we believe her estimation, often go through fifty or more revisions before they arrive on the page in their final form. Klinkenborg suggests forcing revision by turning off the filter almost entirely as one writes. "Write these things down." I suppose the implication is that stream of consciousness, subconsciousness, and the writer's whim are as likely to produce a worthwhile thought as the deliberate part of the mind.
