Writers write. Professional writers write a lot. The StoryADay (http://storyaday.org) challenge exists to help you learn how much you're capable of writing in a month. The Write Every Day, Not "Some Day" podcast helps you figure out how to keep that commitment up for the rest of your life. Each 10-15 minute episode tackles a particular topic and gives you a writing assignment to complete before the next episode.
