Multi-talented British writer, G K Chesterton, said,
"The whole object of travel is not to set foot on foreign land; it is at last to set foot on one’s own country as a foreign land."
Here, the author is suggesting that, when we travel, and in the process open our minds to new ideas and cultures, we can see, upon our return, our country in a new light, see it as travelers from other nations do, and perhaps appreciate it more than we did in the past. I certainly agree with this concept, and it has been echoed many times before in other quotations.
