    Awareness of having better things to do with their lives is the secret to immunizing our children against false values—whether presented on television or in “real life.” The child who finds fulfillment in music or reading or cooking or swimming or writing or drawing is not as easily convinced that he needs recognition or power or some “high” to feel worthwhile.
