For people who are results-oriented, there are two basic rules. The first says that what is important is to achieve the goal, not the effort spent or the time wasted. Achieving the goal in practice means defending the interests in the course of a conflict with the help of adequate means, including power if necessary. The metric for achieving the goal is the security desired and sought by the subjects whose interests are defended with the tools of power. The second rule states that regardless of the result achieved, a benefit can be derived from the lessons learned.
