In "Station Eleven," the author Emily St. John Mandel explores the theme of unfulfilled potential in adulthood. Many individuals find themselves living lives that were shaped by expectations rather than true desires. They reflect on the choices that led them to these paths and experience a profound sense of disappointment, feeling as though they've lost a part of themselves in the process. This disillusionment often stems from responsibilities like mortgages and family commitments that bind them to their current situations.

These characters can be likened to "high-functioning sleepwalkers," moving through life without genuine engagement or joy. They are aware of their desires for change but feel trapped by circumstances, which creates a haunting sense of regret. This commentary serves as a poignant reminder of the complexities of adulthood and the often-great weight of societal expectations that can overshadow personal aspirations.
