We're taking some time off to bring you even more episodes of A Bit of Optimism that you're going to love! In the meantime, we're revisiting some of our favorite episodes, like this one with Harvard professor Robert Waldinger. We all want to live a happy life. But what does the research say about how to achieve it? For more than 86 years, researchers at Harvard University have been trying to figure out how humans can live happier lives.  In one of the longest-running and most comprehensive studies of human happiness, Harvard tracked 724 teenagers through every stage of their adult lives since 1938. Some of them are still alive today and the findings are clear: lasting happiness isn’t about wealth or fame—it’s about something much deeper. Robert Waldinger, a professor and psychiatrist, has directed the study for over 20 years. His TED Talk about it went viral with nearly 50 million views, and in 2023, he wrote a book about it - The Good Life: Lessons from the World's Longest Scientific Study of Happiness.I asked Robert to share what the study has revealed about happiness over the decades, how its insights have shaped his own life, and the one essential ingredient for a joyful, meaningful existence. This…is A Bit of Optimism. To learn more about Robert and his work, check out: The Harvard Study of Adult Development robertwaldinger.com
