I'm a Harvard MBA who left the tech world in 2006 to pursue a more fulfilling mission: visit every country in the world and share their unique lessons with whoever gives a crap. I've written Hike Your Own Hike: 7 Life Lessons from Backpacking Across America. I've walked across America four times and visited over 80 countries. I'm the first guy to yo-yo the Continental Divide Trail. I also thru-hiked the Pacific Crest Trail and Appalachian Trail southbound. I've walked across Spain twice. In 2008-2011, I traveled in Eastern Europe and wrote my second book, The Hidden Europe: What Eastern Europeans Can Teach Us. I'm currently on a 4-year trip to visit all 54 countries in Africa.
