The quote from Alexander McCall Smith's "Blue Shoes and Happiness" emphasizes the significance of experiencing happiness and the ability to reflect on it later. It suggests that moments of joy are valuable not only in the present but also in how they linger in our memories. This duality highlights the importance of both the experience and its recollection in our lives.

Furthermore, the statement implies that happiness can serve as a source of strength and comfort when faced with challenges. By cherishing happy memories, individuals can find solace and motivation, reinforcing the idea that life encompasses a mixture of joy and adversity.
