Law 4 states that you should always say less than necessary. This principle emphasizes the power of brevity in communication. By speaking less, you create an air of mystery and intrigue, making others more curious about your thoughts and intentions. This can enhance your influence and authority in conversations. Additionally, saying less can prevent misunderstandings and reduce the risk of revealing too much information. When you keep your words concise, you maintain control over the narrative and allow others to fill in the gaps, which can lead to greater respect and admiration for your insights.
