Rick is a guy who knows what he likes and what he wants. He is not ashamed of trying to obtain precisely what it is that he wants and he is willing to face challenges to get what he wants. A healthy child learns that he can't always have what he wants, but a good parent will not shame a child for expressing his desires, even when they cannot be fulfilled. So Rick represents that healthy child who can feel good about his desires, can express these desires without shame and can face obstacles that may appear in the way of obtaining those desires and who accepts the possibility that not all desires can be fulfilled.
