There is this moment on my Ha Long Bay cruise. Skipping the start of dinner, I go to the lower deck to just soak in the view without having to feel self-conscious about whether or not I should be talking to the other passengers or whether I should be admiring the bay. Anyway, alone down there, it's spine-tingling -- the last light following sunset dims out in the clouds and shades the rock formations into gradients of gray, charcoal and finally black.
Perhaps the right thing to say is traveling gives you different perspectives. But in most cases, traveling won't make you a better person: if you're a judgy, greedy one, unless you experience something terribly life-changing like an Afghan prison, you'll still be judgy and greedy. Perhaps even worse.
