In the quote from David Mitchell's "Cloud Atlas," the idea is presented that individual lives may seem insignificant, like a single drop in an infinite ocean. This metaphor suggests that while one person's existence might feel minor, it contributes to the larger tapestry of humanity, much like each drop contributes to the ocean's vastness.

The metaphor emphasizes the interconnectedness of all lives, illustrating that every person's experiences and contributions matter. Each drop symbolizes the collective impact of humanity, highlighting that every individual's life has value and plays a role in the greater whole. This perspective encourages us to recognize our importance in the world.
