Eventually, the threads of a screw strip out and the screw's head is tapped out from too much rough turning.  Ruined, irreparable.  We all feel like that busted screw sometimes.  We feel that way precisely because we are not made of steel - we feel and are flesh and blood.  And that is our rescue: we heal.  Our threads come back into neat alignment and our heads return to the ready unless we mistake ourselves and our substance.
