"It's so gray that you begin to think, 'You know what, I need to go about this in a different way. I need to have someone around me who has some awareness that can explain some of these rules. Because I know what the rule is, but then it's ruled differently. Either I'm going to drive myself nuts trying to figure this out, or you get someone who speaks that language."
