The person with the most flexible behaviour will win. Most changes in outcome start with changes in behaviour. An incapacity for change, lack of flexibility, equates to a diminishing outcome since the circumstances that originated the behaviour are not static, they are constantly evolving. Therefore time, and the resulting changes that come with it, create a widening gap between the circumstances you find yourself in and your ability to deal with them. At best you may produce an outcome that remains constant as compared to those with flexibility of behaviour who are finding ways to produce more with less over time.
An indicator of flexibility of behaviour is the ability to deal with obstacles. Are they the way, or the wall.
