This reminds me of a story of Diogenes the Cynic [1], who embraced minimalism to the point that he slept in a large wine jar and owned only a few simple possessions, such as his tunic and a drinking bowl. One day, he saw a boy drinking water from a trough by cupping his hands and bringing it to his mouth, so Diogenes threw away his drinking bowl and stated that the boy had found true minimalism because "nature had already provided him with a cup."
