Consider a painting by Rembrandt or a bronze by Degas or a violin by Stradivarius or a play by Shakespeare. They all have great value for two reasons. One, their creators were masters and second, they are few in number. But there is more than one of each of them. On that reasoning, you are the most valuable treasure on the face of the earth, for you know who created you and there is only one of you. Never, in all the billions of humans who have walked this planet since the beginning of time, has there been anyone exactly like you. Never, until the end of time, will there be another such as you. You are the rarest thing in the world.
