The quote emphasizes the importance of personal agency in achieving happiness, suggesting that ultimately, the responsibility for one’s joy lies within oneself. It reflects the idea that external circumstances or other people may influence our feelings, but true contentment comes from self-discovery and personal growth. This realization empowers individuals to take control of their emotional well-being.

Moreover, the phrase "it is never too late to find out how to do it" offers hope and encourages continuous self-improvement. No matter where someone is in life, there is always an opportunity to learn and change for the better. This notion, highlighted in Ruth Reichl’s "Not Becoming My Mother," inspires readers to seek happiness actively and reminds them that the journey towards fulfillment is ongoing and accessible at any stage.
