For 498 days, Michael Zervos woke up in a new country almost every morning, chasing not just a world record but a deeper understanding of human joy.

The 35-year-old American, who also holds Greek citizenship, set out to break the Guinness World Record for the fastest time to visit all sovereign countries—198 in total. He completed the journey in just 498 days, earning two titles: fastest time to visit all sovereign countries (overall) and fastest time to visit all sovereign countries (male).

But Zervos wasn’t just travelling for the sake of speed.

“I wanted to explore happiness from a global perspective,” Zervos told the Guinness World Records, reflecting on his own struggles with depression during the pandemic. “What if I collected these stories and shared them with others around the world as I travelled?”
