In Invisible Cities, Calvino has Marco Polo describe fifty-five fantastical cities to Kublai Khan — cities of memory, of desire, of signs. Cities built on stilts, cities repeated identically, cities you only see when leaving.
Near the end comes the twist: every city he's described is secretly Venice. One place, seen fifty-five different ways.
The lesson isn't just literary. You don't see the world as it is — you see it through the lens you carry. Change the lens, and the same street, the same job, the same person becomes a different city entirely.
