The essence of happiness, as highlighted in Brad Thor's "Act of War," can be distilled into three fundamental elements. First, having engaging pursuits or activities in life provides a sense of purpose and fulfillment. These can range from careers to hobbies that occupy our time and mind, contributing to our overall satisfaction.

Secondly, the importance of relationships cannot be overstated. Loving connections with others enrich our lives, creating support systems and cherished memories. Finally, the anticipation of future events or goals instills hope and excitement, driving us forward. Together, these three aspects—meaningful activities, meaningful relationships, and hope for the future—form the foundation of a happy life.
