Ever heard of the Overview Effect? It’s a shift in perspective that astronauts experience when they see Earth from space. Suddenly, all the borders, conflicts, and differences that seem so significant on the ground, appear so trivial from up there. Travel can give you a mini-version of this effect. No, you don’t have to go to space (though if you can, why not?), but moving out of your comfort zone and venturing into the world is enough to realize just how vast it is.
