We usually try to get ground under our feet. It's as if you were in a spaceship going to the moon, and you looked back at this tiny planet Earth and realized that things were vaster than any mind could conceive and you just couldn't handle it, so you started worrying about what you were going to have for lunch. There you are in outer space with this sense of the world being so vast, and then you bring it all down into this very tiny world of worrying about what's for lunch: hamburgers or hot dogs. We do this all the time.
