A Samurai warrior advises “if your opponent’s rhythm is disorganized or if he has fallen into evasive or retreating attitudes, you must crush him straightaway with no concern for his presence and without allowing him space for breath. It is essential to crush him all at once. The primary thing is not to let him recover his position even a little.”Today’s athletes refer to ruthlessness as the ability of finishing somebody off. Although ruthlessness may be accepted in a sports arena, in other professional environments it has a bad odor because it is almost impossible to determine how much is necessary and how much is excessive. Nevertheless, sometimes it is essential to be ruthless to achieve your objectives.
