J. Grace Pennington, Guest Contributor On the surface, our possibilities may seem unlimited. We can sit down at our word processors and type out anything our imagination can come up with. There are, however, still many possible limitations. We are obviously limited by what we know or can find out about. We are somewhat limited by our own experience (“Write what you know!?”). We may be limited by word count, content, or subject if writing for someone else. But, like Spielberg, we can use these limitations to enhance our creativity and improve our craft.
