It translates limits into an explicit picture of conflict that becomes workable. This produces not just compromises but more elegant principles. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. | With an overloaded day full of too many tasks, a realistic picture of the day emerges.
