John Updike's quote, "Sex is like money; only too much is enough," speaks to the complexities of human desires and needs. It suggests that, much like financial wealth, sexual experiences can become overwhelming if pursued in excess. This analogy highlights how both sex and money can be sought after, yet their true value lies in moderation and balance. Understanding when enough is enough can lead to healthier relationships and personal fulfillment.

The context of this quote is found in Young's book "Initiation," which explores themes of maturity and self-discovery. Throughout the narrative, characters grapple with their desires and the consequences of indulgence. Updike's comparison serves as a poignant reminder that while both sex and money can bring pleasure and satisfaction, their overabundance can lead to complications, underlining the importance of thoughtful engagement in both aspects of life.
