In "The Art of Body Language" by Susan C. Young, the author emphasizes the importance of managing one's energy by establishing boundaries. By simply saying 'no' and minimizing time spent with individuals who are draining, a person can protect their emotional and mental well-being. It's crucial to evaluate how interactions with others affect your feelings as a guide for these boundaries.

The book suggests that recognizing the impact of non-verbal communication plays a vital role in enhancing positive interactions. This awareness can help in creating a more supportive environment and fostering meaningful connections, ultimately leading to better personal and professional relationships.
