While it is absolutely necessary for undisciplined persons to become disciplined, the problem is that they find it very difficult to do so without help because they are caught in the discipline dilemma: it takes discipline to become disciplined. That is why, in the Book of Proverbs, the need for outside help in bringing about discipline is so frequently emphasized. Discipline rarely comes easily. What is needed in most cases is heavy structure, with someone riding herd until the habitual side of the behavior begins to take form. Then the structure may be removed and supervision may be relaxed.
