In John Irving's "Avenue of Mysteries," the character Juan Diego embodies the idea that individuals often underestimate their impact and fame. Despite his modest perception of himself, he has a larger audience and influence than he realizes. This theme resonates throughout the narrative, highlighting the disconnect between self-perception and reality, especially for those engaged in creative endeavors.

The quote suggests that writers, like Juan Diego, often possess a hidden audience that appreciates their work more than they recognize. This can serve as an encouragement for creators to continue sharing their voices, as their contributions may reach and resonate with many, even if they are unaware of it. This reflection on fame and readership reveals the complexities of artistic recognition in society.
