The Sustainable Happiness Model 

The Sustainable Happiness Model is a research-based framework developed by psychologists Lyubomirsky, Sheldon, and Schkade that identifies the three core contributors to lasting happiness: genetic set point, life circumstances, and intentional activities. With 40% of our happiness influenced by actions within our control, this tool empowers individuals and leaders to focus on daily behaviors—like gratitude, perspective-shifting, and value-based routines—that drive fulfillment and emotional resilience. It's a powerful resource for coaching, leadership development, and creating emotionally intelligent teams.
