In "The Full Cupboard of Life," Alexander McCall Smith highlights the discomfort that arises when individuals become overly fixated on a single issue. This obsession can lead to a narrow perspective, preventing them from understanding how their concerns fit within a broader context. Such rigid focus may result in misunderstandings and an inability to engage with the complexities of life.

This observation serves as a warning about the limitations of tunnel vision. It underscores the importance of maintaining a balanced view and considering multiple facets of any situation. By doing so, people can develop a more holistic understanding of the world around them, fostering better relationships and enriching their lives.
