An Astronomer used to walk out every night to gaze upon the stars. It happened one night that, with his whole thoughts rapt up in the skies, he fell into a well. One who heard his cries ran up to him, and said: "While you are trying to pry into the mysteries of heaven, you overlook the common objects under your feet."
Moral : We should never look so high as to miss seeing the things that are around us.
