Greatest Last Line in Literature as opposed to Greatest first Line.

For me, it is The Great Gatsby.

The Line- “So we beat on, boats against the current, borne back ceaselessly into the past.”

Anyone who has read the story would realise how soul crushing this line is. Gatsby continued to row against the current throughout his life for Daisy, got rich, became a society man and a criminal but the past remained ceaseless and irrefutable. One devastating line.
