The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity. We must free ourselves of the hope that the sea will ever rest. We must learn to sail in high winds. If women didn't exist, all the money in the world would have no meaning.
