"Mystery is a resource, like coal or gold, and its preservation is a fine thing"

In this quote, Tim Cahill compares secret to important resources such as coal or gold. He recommends that mystery is not something to be feared or prevented, however rather something to be valued and preserved. Much like coal and gold, mystery has the potential to bring excellent worth and richness to our lives. It permits us to explore and discover new things, and includes enjoyment and intrigue to our experiences. By preserving mystery, we are able to preserve a sense of marvel and interest in the world around us. In this method, secret ends up being a valuable resource that enhances our lives and makes them more fulfilling.
