" No experienced worker in this field will deny that there are rules of thumb that can prove helpful, but they must be applied with prudence and intelligence. One may follow all the right rules and yet get bogged down in the most appalling nonsense, simply by overlooking a seemingly unimportant detail that a better intelligence would not have missed. Even a man of high intellect can go badly astray for lack of intuition or feeling. "
