The sentiment that "life is better when nobody knows anything about you" reflects a desire for privacy and freedom from external judgments or expectations. It suggests that maintaining a low profile can protect you from unwanted attention, interference, and potential exploitation. This perspective emphasizes the value of personal autonomy and the peace that comes from living without the pressures of social scrutiny.
However, this approach also has its downsides. Human connection, trust, and relationships often rely on mutual knowledge and openness. Completely isolating oneself can lead to loneliness and a lack of support. A balanced approach, where one maintains a certain level of privacy while still fostering meaningful relationships, might be a more sustainable way to achieve both peace and connection.
