How often when I am writing do I get up from where I am seated, to walk across the room, away from my desk, impulsively it would seem, only to return to it a few moments later? As if some stoppage in the fluidity with which my work had been proceeding could be resolved, or would resolve itself, if only I imparted to my imagination, by way of my body, a jumpstart or kick, so that whatever configuration of words had till then been floating on the horizon of my brain, just out of reach, suddenly became clear, and availed itself to me.
