"Doing is a quantum leap from imagining. Thinking about swimming isn't much like actually getting in the water. Actually getting in the water can take your breath away. The defense force inside of us wants us to be cautious, to stay away from anything as intense as a new kind of action. Its job is to protect us, and it categorically avoids anything resembling danger. But it's often wrong. Anything worth doing is worth doing too soon."
