The quote reflects the transformative nature of human identity, emphasizing how we evolve over time. Each decade marks a significant change in who we are, suggesting that our past selves are essentially different beings. Memory serves as the only link to those previous identities, enabling us to recall who we once were, despite our continual growth and renewal. This idea suggests a constant shedding of old personas, leading to the emergence of new selves.

Moreover, the message underlines the impermanence of identity. It illustrates that while we carry memories that connect us to our past, our present selves are shaped by new experiences and challenges. Ultimately, the journey of life is about adaptation and change, reinforcing that we are not only shaped by our histories but also actively become our future selves, continually evolving away from our former identities.
