Milan Kundera's quote from "The Unbearable Lightness of Being" highlights the inherent limitations of human desire. It suggests that since we experience only one life, we are unable to assess our wants through past lives or anticipate them in future ones. This singular existence makes it challenging to determine the true nature of our aspirations and priorities.

The idea emphasizes the complexity of choosing what we truly want, as we lack any comparative framework. We cannot refine our desires through experiences of different lives; thus, we often find ourselves navigating uncertainty about what will bring us fulfillment. This reflection raises profound questions about the nature of existence and choice.
