The Greeks had a word for the only immortality they believed a person could earn. They called it kleos, which meant roughly, "that which is heard." The fame that outlives you, carried forward in story and song.
Their heroes understood the bargain. Achilles was offered a choice: a long, comfortable life no one would remember, or a short one that would be told forever. He chose the story. To the Greeks, a hero was a mortal who knew he would die and decided to matter. And the only way to matter was to be worth telling.
I think about this often, because it hasn't really changed. We still build monuments out of narrative. A man's history, a life's work, and none of it survives on facts alone. It survives because someone shaped it into a story good enough to repeat, reinterpret and adapt.
The song is still the point.
And one of the most enduring songs the Greeks ever told was that of Odysseus, in Homer's legendary Odyssey, a perfect example of what we now call the hero's journey. It's a storytelling template that turns up everywhere, in myths, epics, and modern movies alike.
It goes something like this: a hero leaves the familiar world, is tested through a series of trials, is transformed by them, and returns home changed, carrying something of value back. At its core it's a story about growth, the outward adventure mirroring an inner one.
Part of why it endures is that the pattern feels true. It maps onto how real change actually happens. We're pulled out of comfort, we struggle, and we come back different. Still, it's best treated as a lens, not a law. Plenty of great stories don't follow it, and leaning on it too mechanically produces the formulaic and the predictable. It is no doubt a useful map, but never a substitute for the actual terrain of a particular person's story. People change, some people don't.
