There are three huge gates that lead into the Cathedral of Milan. Over one gate there is an inscription in marble under a beautiful flower bouquet that says, "The things that please are temporary." Over the second gate, there is a cross with this inscription: "The things that disturb us are temporary." However, over the central gate, there is a big inscription saying, "Eternal are the important ones."
As if you could kill time without injuring eternity.
Henry David Thoreau.
