And now here is my secret, a very simple secret: It is only with the heart that one can see rightly; what is essential is invisible to the eye.
Antoine de Saint-Exupéry
In the beloved French novella The Little Prince, a pilot who has crashed in the desert encounters a young prince visiting Earth from his home asteroid. The premise was inspired by author Antoine de Saint-Exupéry's (born June 29, 1900) own desert crash. After three days without water, he was saved by a passing Bedouin.
