Good post Mike,
I would add that strength, as you defined it (energy, talent and passion), is also released when an individual is in the right working environment and structure and their strength is restricted when an individual is in the wrong working environment and structure. When a leader seems to achieve twice as much as others, they almost invariably have a work style match, a heart match with the organization’s vision, a talent match for the task at hand and spirit match with the leadership and their peers.
