In Haruki Murakami's novel "Norwegian Wood," the author emphasizes the significance of the ages nineteen and twenty as formative years that greatly influence one's character development. During these years, individuals are particularly impressionable and the choices they make can shape their future selves. Making poor decisions or being negatively influenced at this stage can lead to lasting emotional struggles later in life.

This reflection highlights the importance of self-awareness and the need for guidance during this pivotal period. By acknowledging the potential for character distortion at a young age, Murakami suggests that nurturing resilience and integrity at this time is crucial for a healthier, more fulfilling adulthood.
