The Little Prince by Antoine de Saint-Exupéry A fragment that perhaps serve you to reflect: Once in the Earth, The little Prince finds a garden of roses and gets depressed, because he thought that was rich, with a flower that was unique in all the world; but his rose was a common rose. The little Prince knows to the fox, who teaches to him the real sense of the friendship and the extract of the human relations, tells to the Little Prince that its rose is the only and special because it is the one that he loves. In its farewell, the fox gives him its secret: Only with the heart it is possible to see well. The essential thing is invisible for the eyes. Antoine de Saint-Exupéry. The Little Prince, pág. 83.
