Like many meticulous people, Cameron thought of himself as merely organized. He certainly did not consider that he took great pains over anything, he did just enough to get it right. Exactly right, of course, for as he was fond of telling his staff, "if it's not exactly right, it's wrong". Occasionally a worker might whimper faintly on hearing these words, because it meant another hour or so of going over the same bit of work, correcting the mistakes which Cameron had patiently pointed out. And doing the corrections exactly right of course.
