What is there to do, waiting for that spark of inspiration needed to fire up a story? Tradition would dictate a glazed look vaguely in the direction of a blank sheet of paper emerging from a typewriter. A blank page on a computer screen works well, although it lacks that drama made famous in "The Shining."
Then there's rearranging (as opposed to organizing). There is no end to the miscellaneous tasks, also known as The To-Do List. The benefit here is in the feeling of accomplishment, not to mention maybe a certain amount of righteousness when items, however trivial, get checked off the list. Somewhat more guilt-inducing are the social networking sites, although networking is how to get that novel sold. So maybe social networking is a good thing between those sparks of inspiration. These, of course, are simply ways of occupying our appropriate free time until the muses see fit to come visit.
On the other hand, there is a heretical, contrarian school of thought claiming that inspiration is not first, followed by a huge amount of frenzied writing, accompanied by red eyes and drooling lips. They say the writing comes first, in a disciplined and focused fashion, and that inspiration comes as a result of this applied effort. Oh, say it isn't so!
