Confidence Classic: What 80+ Years Of Research Says About Happiness with Dr. Marc Schulz

from Creating Confidence with Heather Monahan · host Heather Monahan | YAP Media

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. In This Episode You Will Learn The #1 predictor of happiness and health, according to 85 years of research from the Harvard Study of Adult Development. How loneliness can impact your health as much as smoking or obesity. The first step to building a happier life. Why even small daily interactions can improve your well-being. How meaningful connections can support brain health and slow cognitive decline. Why money and career success don’t predict long-term happiness. The surprising reason people often become happier as they age. How to evaluate your “social fitness” and strengthen your relationships. The most common regret people share in their 80s. Why it’s never too late to build stronger relationships or expand your social circle.
