Ideas flow from writers like water from a tap. Every so often, when we want to capture an idea and turn it into a story, we put a stopper in the sink to collect the words, sentences, and scenes that will fill the sink and complete the story.
Sometimes the creative tap is wide open and the story sink fills quickly. Sometimes the faucet merely drips and the sink does not fill for a long, long time. Often we have several faucets filling several sinks concurrently.
What I've come to realize is that it doesn't matter how quickly or how slowly each story sink fills. Often no one, not even the writer, will recognize which story sinks filled quickly and which filled slowly because each writer's sinks are filled from the same creative source.
So, stop up a few of your story sinks and start capturing the flow of your creativity.
