改变世界的阻碍，并非人类的冷漠，而是世界实在太复杂。
    要关心转变为行动，我们需要看到一个问题，发现解决办法，看到的影响。但是世界的复杂阻止所有三个步骤。
    如果我们真正发现了问题，这是第一步，我们来到第二个步骤：通过复杂的事件中找到解决办法。
    从这个复杂的寻找解决办法，可以分为四个步骤：确定目标，找到最高效的方法，发现适用于这个方法的理想技术，并在此期间，充分利用已有的技术，你最聪明的应用 - 无论它是复杂的药物，还是最简单的蚊帐。
    最后一步后，发现问题和找到解决方法 - - 是衡量你的工作和分享你的成功和失败的影响，让别人从你的努力学习。
    但是，如果你想激励其他人参加，你就必须拿出更多的统计数字;你必须展示你的工作对人的影响 - 所以人就会感到拯救一个生命，什么途径向受影响的家庭。 
    The barrier to change is not too little caring; it is too much complexity.
    To turn caring into action, we need to see a problem, see a solution, and see the impact. But complexity blocks all three steps.
    If we can really see a problem, which is the first step, we come to the second step: cutting through the complexity to find a solution.
    Cutting through complexity to find a solution runs through four predictable stages: determine a goal, find the highest-leverage approach, discover the ideal technology for that approach, and in the meantime, make the smartest application of the technology that you already have — whether it’s something sophisticated, like a drug, or something simpler, like a bednet.
    The final step – after seeing the problem and finding an approach – is to measure the impact of your work and share your successes and failures so that others learn from your efforts.
    But if you want to inspire people to participate, you have to show more than numbers; you have to convey the human impact of the work – so people can feel what saving a life means to the families affected.
