Lisa Marranzino was a therapist in Denver when she realized something was missing in her life. It might have been mid-life crisis. Whatever it was, she decided to explore the world and find what made people happy, both for herself and her patients. That started a five-year odyssey in which she traveled to over 40 countries, spoke to scores of strangers in intimate conversations, and tried to find a common theme to what brings people happiness in all cultures. She documented her conversations in her book, Happiness On The Blue Dot.   In this podcast, Lisa shares her experiences as a world traveler, and offers suggestions for interacting with strangers from around the world.
