The protagonist reflects on a common saying about the importance of movement and progress. She questions whether this notion holds any real truth or if it's simply another cliché, perhaps misleading. The idea that one must always seek change seems to lack substance, especially when she feels content in her current position.
As Mma Ramotswe, she takes pride in her role as a detective and a wife to a skilled mechanic. This sense of satisfaction leads her to believe there is no pressing need to move on or pursue anything else when she is already fulfilled in her life. The comfort of her existing situation brings forth a contemplation of the value of stability versus the societal push for constant advancement.
