The quote from Antoine de Saint-Exupéry's "Night Flight" expresses a profound philosophical reflection on the nature of existence and the human experience. It suggests that rather than longing for eternal life, individuals seek to find meaning in their actions and the world around them. The fear of meaningless existence can lead to a deep sense of emptiness, which is a poignant concern shared by many. It highlights the importance of purpose and significance in life.

Moreover, this quote underscores the idea that the sudden realization of life's inherent emptiness could be devastating. By emphasizing the value of meaning, Saint-Exupéry invites readers to contemplate their own lives and the impact of their choices. The protagonist's journey is not merely about survival or success; it's about understanding and cherishing the significance of their experiences and relationships.
