In Cecelia Ahern's "The Book of Tomorrow," the author highlights the empowering nature of hope. Rather than portraying hope as a weakness, she presents it as a source of strength that instills a sense of purpose in life. Hope helps individuals find reasons to persevere, even when faced with despair. This optimistic outlook encourages one to envision a future that could improve, alleviating feelings of hopelessness and despair.

Ahern emphasizes that while one may suffer from loss and uncertainty, the mere possibility of a better tomorrow can be transformative. The idea of 'maybe' serves as a lifeline, asserting that circumstances may change for the better, thus providing motivation to endure hardship. This perspective instills a belief that life can improve, making the challenges more bearable and reinforcing the notion that hope is a crucial element of resilience.
