JA editorial note on change: We live in the world that we perceive. Our limits are the limits of our perceptions. This generation knows more than any previous generation. Its actions will eclipse those of previous generations. We change the world by observing its behavior, thinking about our observations and acting on our thoughts. To observe we must open our eyes. To think we must open our minds. To act, we must open our hearts. Our eyes have never been so wide. Our minds never so trained. And the courage in our hearts spreads like a contagion.
