"Chance favors the prepared mind."
Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.
我們活在最好的世界中，因為它是由一切可能性中選擇而來的。
The world is a book, and those who do not travel read only one page.
