The video is about the art of happiness and features guest speaker Robert Mack, a positive psychology expert. Mack's approach to happiness is rooted in personal and professional experiences, as well as scientific research. He introduces the happiness formula, which states that happiness (H) is equal to genetic set point (S) plus conditions and circumstances (C) plus volitional activities (V). Genetic set point accounts for 50% of happiness, conditions and circumstances for 10%, and volitional activities for 40%. Mack emphasizes that happiness is within our control and can be built through volitional activities.
