The Little Prince - my favourite book since I was a little girl. “Goodbye,” said the fox. “Here is my secret. It’s quite simple: One sees clearly only with the heart. Anything essential is invisible to the eyes. . . . It’s the time that you spent on your rose that makes your rose so important. . . . People have forgotten this truth,” the fox said, “But you mustn’t forget it. You become responsible for what you’ve tamed. You’re responsible for your rose. . . .”
