I think that if you have a knack for storytelling, and you work really hard at it, you'll have a chance to tap into something deep. But the fact remains that good sentences are hard won. Any writer worth a lick knows constructing a sentence, a paragraph, or a chapter is hard work.
Writers do well to carefully attend to those moments of inspiration, because chances are that they're writing from a very deep place. The subsequent search that ensues to continually attend to that voice that you hear is what is going to give the story drive.
