This may not be the norm, but I think to me the most impressive thing as an American who grew up without ever leaving the country was backpacking through villages in Central America and seeing that no matter where you go, it's just people living their lives. They may be poorer, speak a different language, and have different customs, but none of that matters much. Everyone is just going through their daily routine. There's not much of a difference between that guy over there and yourself.
