This document discusses the importance of self-knowledge and how difficult it is to achieve in modern life. It argues that true self-knowledge requires constant introspection and learning about oneself throughout life. However, today's fast-paced world leaves little time for reflection. People are constantly surrounded by others and come to understand themselves based on the opinions of family and friends rather than taking the time for solitary self-reflection. The document stresses that solitude is essential for gaining self-knowledge, as it is only when alone that people can truly think about who they are, what they want from life, and their inner desires and strengths/weaknesses.
