Your legs are already half out the door while your head insists on getting the sentence right first. Mars sits at one pole with the body that bolts, Mercury at the opposite with the mind that wants the words in order. Move, and a voice picks apart what you just did. Think, and the muscles twitch with the wait. So you act without ever explaining, then explain, flawlessly, something you no longer do. In the end you let the body be the evidence and the head be the compass. A clean decision carries both at once: legs already walking, mind that knows the street. Walk thinking. Think walking.
