We are all completely unique. This means that each one of us brings something unique to the table and each of us contains a piece of the puzzle. Using this logic we can infer that each person possesses some skill in which they are the best in the world, even if that skill is immeasurably nice. It could be creating paper art using recycled materials, organizing tiny bookshelves extremely efficiently, finding the best (but most obscure) movie references for any occasion, or communicating complex ideas to children.

Everyone in the world has something.
