Formulate the problem and define the essence of the right. When I think about the essence of the problem, I am reminded of sumo wrestlers - huge, powerful Japanese. Most of the time they fight squat, scrutinizing each other. The fighters take position, keep it for a while, then get up and go back squats. This is repeated many times, and suddenly - bang! - They grab each other, one falling on the mat, and the match is over. In the process of squatting and making various poses fighters looking for the right position of the body, trying to focus optimally to meet adequately the brunt. The only protection a sumo wrestler is to maintain the correct "alignment", always ready to surprise attack and to provide immediate rebuff. Similarly, in the process of formulation of the problem, you can write the wording to study it, to put aside, to come back to it later, "stretch" or "shrink" it, reformulate, while "alignment problem" is not defined correctly. Then you, like a sumo wrestler, ready for battle.
