"In love, as in gluttony, pleasure is a matter of the utmost precision"

This quote by Italo Calvino suggests that both love and gluttony include a lot of accuracy and attention to information. In both cases, pleasure is stemmed from the mindful choice and enjoyment of the experience. In love, this might mean making the effort to learn more about somebody, comprehending their likes and dislikes, and finding ways to make them feel unique. In gluttony, it could imply picking the best ingredients, preparing the food with care, and savoring each bite. Both activities require a particular level of precision and attention to detail in order to make the most of the pleasure derived from the experience. Eventually, Calvino is recommending that satisfaction is something that requires effort and consideration in order to be truly enjoyed.
