A destination needs desire. To reach it requires will. The wanderer has will without desire, to move without getting anywhere, but to keep moving. One is always closer by not keeping still, says Thom Gunn. The wanderer tells himself that his aimless errancy is better than the inverse, desire without will. That would be simply to yearn, boundlessly longing for what can never be reached. Perhaps he feels that to keep moving is more heroic, less worthy of pity. It is not.

Rather it is like the shark who must keep moving, moving to breathe, moving to stay afloat, or else sink, into the dark blue depths, under the weight of endless tons of water, where even the light of the sun, if it could reach that far down, would be pale and cold.
