Three people, three stories, one shared question: what does it take to move toward happiness?
I met them along the road during my run across Europe in 2025, and they were generous enough to let me point a camera at the answer.
David Green is a retired entrepreneur, long-distance runner, and writer who has completed numerous ultra events including solo runs across the United States, Brazil, and Spain—and is now preparing to cross Europe on foot. His love of movement, adventure, and open roads is matched only by his bond with dogs. In 2022, he and his wife, Mônica, founded Friends of Lucky Caminho, a nonprofit that helps rescue stray dogs along Brazil’s Caminho da Fé trail, where he first met Lucky. David lives in Florida and Portugal with Mônica and their three rescue dogs. A portion of this book’s proceeds supports the charity.
