That we leave our homes, that we step through our doors to the world, that we travel our whole lives not because we want to collect exotic T-shirts, not because we want to consume foreign adventure the same Western way we consume plastic and Styrofoam and LCD TVs and iPads, but because it has the power to renew us—not the guarantee, not the promise, just the possibility. Because there are places our imaginations can never construct for us, and there are people who we will never meet but we could and we might. It reminds us that there is always reason to begin again.
