" ...because you are not trying simply to complete a set of books or toys or Weetabix cards, you are trying to complete yourself, to get back to the whole person you were before, as a child, before the obstructions and compromises of adulthood got in the way. And yet, all you are really doing is accumulating a pile of crap, souvenirs of the futility of the quest. "

― Neil Perryman , Adventures With the Wife in Space: Living With Doctor Who
