Based on the teachings in Chapter 8, what constitutes a wasted human life, and what is the path to making it successful?

Chapter 8 of the Sai Satcharitra presents a clear distinction between a wasted life and a purposeful one. A life is considered wasted if it is spent merely on the four activities of eating, sleeping, fear, and mating, or consumed by childhood play and youthful passion without a higher goal. Such an existence is equated to that of animals. According to the teachings in this chapter, the path to a successful life is the realization of the Eternal and the attainment of the Supreme Self (Paramatman). One must seek to answer the fundamental questions of "Where have we come from? Who are we?" to be truly proficient and avoid a life of mere exhaustion.
