In John Steinbeck's "Cup of Gold," the character reflects on the complex nature of ambition and self-identity. The quote suggests that despite achieving great things, the individual may still possess childlike desires and fantasies, indicating that true maturity may be lacking. Achieving greatness does not necessarily equate to being truly grown-up or self-aware.

This perspective implies that the pursuit of lofty aspirations can sometimes lead one to remain emotionally underdeveloped. The notion of wanting "the moon" symbolizes untamed dreams and an insatiable longing that prevents the character from realizing his full potential as an adult. It raises questions about what it means to grow and evolve beyond simple desires.
