worry is different (in my mind) than planning. Worry does not
   achieve results. it is a loop that circles back upon itself.
   Planning, goal-setting, seeing the result in the mind or paper
   or computer and then working towards making that goal real, is
   not worry. Coping is also different from worrying. Coping is
   living for today and, presumably, achieving in the moment with
   whatever affordances are at hand.
