In "The Lost World," Kelly observes Sarah's relentless determination and resilience. Sarah's approach to challenges—refusing to be hindered by obstacles or the opinions of others—leaves a significant impression on Kelly. This inspiring attitude ignites a shift in Kelly, encouraging her to adopt a similar mindset of confidence and independence.

By imitating Sarah, Kelly starts to embrace the idea that she can pursue her desires and ambitions without being held back by self-doubt or external criticism. This transformation reflects the book's broader themes of empowerment and the importance of perseverance in the face of adversity.
