For many travelers, setting a budget marks one of the first steps of a journey. But for Leon Logothetis' globe-trotting adventure, his allowance was simple, and stark: $0. Logothetis, 40, instead relied on the generosity of strangers for food, transportation and lodging a journey documented in the Netflix series "The Kindness Diaries." Though the show's travels took place in 2013, Logothetis is comfortable on the open road, having quit his job as a London broker back in 2005. So far, he's visited nearly 100 countries. "I started doing this because I was in a lot of pain " emotional pain," he told TODAY. As someone who worked in finance, Logothetis appeared to have everything he could possibly want, but it was a different story on the inside. "I was wearing a mask, as many of us do," he said. "I felt very alone, very depressed, (with) no real sense of purpose." One of the most emotional moments on Logothetis' journey involved a homeless man named Tony. Though he had almost nothing, Tony shared what little he did have, including his shelter and some of his belongings. "The greatest lesson I learned was that we're all the same," said Logothetis. "It doesn't matter what religion you are, doesn't matter what color you are, doesn't matter where you live. Each person wants to be seen, wants to be loved, wants to be valued, wants to be heard." While it's important to remain vigilant and trust your intuition, Logothetis says what you see on the news shouldn't "cloud the ability to go out and have a transformational experience. You would imagine that America is a mean place ... You would imagine that ... people don't care about each other. That is totally untrue." And the same goes for countries around the world. "There is connectivity out there, and there's kindness out there," he said. "And that was one of the greatest lessons I learned."
