Often, this will be preparation for a challenge to the limits, or a changing over t a new set of constraints. Whenever one comes upon the circumference, it is best to consider carefully and marshal one's resources before crossing the line. There is always uncertainty, and we must be wary. We can also utilize limits for our own purposes. We can trap someone because we know of the limits ahead.
Defense is possible by utilizing given limits, as a wall protects our backs in a fight.
Work is easier when we know that we will be working for a limited time. We can take advantage of opportunities because we know that they are only there for the moment. Limitations should not always be seen as negative constraints. They are geography of our situation, and it is only right to take advantage of this.
