What actually makes people happy and healthy over the course of a lifetime? In this episode, I sit down with Dr. Mark Schulz, Associate Director of the Harvard Study of Adult Development, to share the findings from the Harvard study that breaks down why the quality of our relationships has the greatest impact on our happiness, health, and even how long we live. We also talk about loneliness, the role of friendships and everyday connections, and why it’s never too late to strengthen the relationships that matter most. Get ready to rethink happiness and discover why the strongest predictor of a good life is the people you choose to connect with.
