In the excerpt from "Housekeeping vs. the Dirt" by Nick Hornby, the author reflects on the significant impact literature can have on individuals. He expresses a desire to create a book that evokes strong emotions, even to the point of provoking outrage. Hornby challenges the notion that literature is unimportant, suggesting that it can deeply affect readers' lives and perspectives.

Despite this ambition, Hornby acknowledges a sense of irony in his self-assessment. He admits that readers might feel disappointed or regretful after investing time and money in his work. Ultimately, he humbly doubts that he has the power to truly ruin someone's life through his writing, even as he welcomes any evidence to the contrary.
