What metaphor is used to describe the unpredictable nature of life?

The metaphor "Life compared to a race" effectively conveys the unpredictable nature of life, aligning with the central themes of "The Art of Racing in the Rain." This comparison emphasizes the idea that life, much like a race, is filled with unexpected turns, obstacles, and challenges that one must navigate. Just as a driver must remain focused and adapt to changing conditions on the racetrack, individuals must also be prepared to face life's uncertainties and respond with resilience and determination. This metaphor illustrates the dynamic nature of existence and highlights the importance of perseverance, especially in the face of adversity.
