Wonder causes us to gape. We can no longer keep such a tight hold on life when, just as in yawning, our mouth is wide open. The more I have come to realize how little I know of this life, the more curious I have grown. If we are curious, we at least know that our heart is still beating. Curiosity opens doors and connects us to the larger life of the world. It is a key as much to this moment as to some grand project that can last a lifetime. It allows us to follow our nose, and there's pleasure in that. We wonder what lies around the corner or over the hill; we wonder what the empty canvas, the unhewn block of stone, conceal that our imagination may reveal. We wonder about that man, or that woman, we saw on the subway.
