Each time you find something that doesn't work, you are better able to recognize a solution that is both good and original. Seize the moment of inspiration. Flaubert's statement also shows that most of us rarely have the time for active inactivity, and cannot succeed at the rate of eight pages in a week. The muse has a lousy sense of time and timing. Let's be realistic.
Originality is, by definition, rare, even in the lives of creative writers.
While they wait, they slug it out every day. It's better for us less talented writers to hang in there and keep writing, than to just hang, waiting for that moment of godly inspiration.
