Seoul Metro has poetry printed on most of the safety doors on the platforms. Some poems are good, some are puzzling, some are thought provoking. This one spoke to me that day. I wish I could translate it to exactly convey the feeling, but poetry really doesn't translate well unless in the hands of a brilliant writer.
"Empty Thoughts" by Jung Wijin
Upon the swift steed called time
I furiously ran
sometimes hastening to go faster
with whipping of my hand
have I sped too much
before my eyes appears the divided path.
