“Consider a lighthouse. It stands on the shore with its beckoning light, guiding ships safely into the harbor. The lighthouse can't uproot itself, wade out into the water, grab the ship by the stern and say, "Listen, you fool! If you stay on this path you may break up on the rocks!" No. The ship has some responsibility for its own destiny. It can choose to be guided by the lighthouse. Or, it can go its own way. The lighthouse is not responsible for the ship's decisions. All it can do is be the best lighthouse it knows how to be.”
