This is the feeling when I’m on the subway, and I look up into the city, skyline, which is infinite.
For example, the very optimistic thought I have is this: even if you try to visit every Seoul subway stop, and did it religiously every day for a year, you would still not run out of places to visit.
To take this thought further, there are infinite cities around the world for you to discover.
