The author reflects on experiences in Antwerp, Amsterdam, and Paris that helped her gain perspective on the vastness of the world. In Antwerp, she and friends gazed up at the towering Cathedral of Our Lady and felt fortunate to be traveling. In Amsterdam, she got lost searching for the Van Gogh Museum but observed the city. In Paris, she watched the sunrise reveal the Eiffel Tower and reflected on feeling small in the immense universe. These moments made numbers like city sizes feel real and showed the hugeness of the world we explore.
