Summary
Analysis
The little prince next meets a merchant who claims to sell a pill that will quench thirst, thereby saving fifty-three minutes a week. The little prince retorts that if he had fifty-three extra minutes, he would use it to walk to a spring of fresh water.
While grownups are only interested in destinations and achievements, the little prince recognizes that the process of exploring and finding water is sweeter than the lack of thirst that comes from drinking.
