Journeys from which one can never return.
Treasures that can never be reclaimed.
Lives that can never come home.
Nearly all things in this world will never go back to the way they once were.
Understanding that, people still continue to get up and take another step forward.
Spurred on by the thought of viewing a landscape they've never seen before,
they keep on walking.
A longing for the unknown, you see, is something no one is capable of keeping down.
