learn from extradinary military man Rossmann
he spent much more time analyzing various targets of opportunity than actually firing at his quarry. He attacked only when he was in the best possible position to win. Then he would focus at all his resources at the idea target – the one that would give him the maximum return on his investment. This is so called “see and decide prior to firing” method. It also explains how he survived 1425 combat missions, yet he was never even wounded.
