"Travel is the only education": I don't recall who said this, but it's stayed with me as containing some important insight. Perhaps because different places and different cultures are so incredibly and diversely generative. You stand in the Imperial Garden in Tokyo, and you're just immersed in this incredible depth around you. And then you visit the Strip in Las Vegas, and there's an entirely different type of depth. Even you can't articulate it, you can feel it, and it's reflected all around.

Something I don't like about the phrase is that it has medicinal, do-this-it's-good-for-you overtones. But good travel is refreshing and rejuvenating; it shouldn't be done for puritanical, let's check-off-the-checkboxes reasons.

Countries visited: Australia, Austria, Canada, England, France, Germany, Ireland, Italy, Japan, Mexico, the Netherlands, New Zealand, South Korea, Spain, Switzerland, United States, Wales.
