要實現這個新的目標，又可以採用新的四步循環。這是一種模式。關鍵的東西是永遠不要停止思考和行動。我們千萬不能再犯上個世紀在瘧疾和肺結核上犯過的錯誤，那時我們因為它們太複雜，而放棄了採取行動。
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.
在發現問題和找到解決方法之後，就是最後一步——評估工作結果，將你的成功經驗或者失敗經驗傳播出去，這樣其他人就可以從你的努力中有所收穫。
you have to have the statistics, of course. you have to be able to show that a program is vaccinating millions more children. you have to be able to show a decline in the number of children dying from these diseases. this is essential not just to improve the program, but also to help draw more investment from business and government.
當然，你必須有一些統計數字。你必須讓他人知道，你的項目為幾百萬兒童新接種了疫苗。你也必須讓他人知道，兒童死亡人數下降了多少。這些都是很關鍵的，不僅有利於改善項目效果，也有利於從商界和政府得到更多的幫助。
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.
但是，這些還不夠，如果你想激勵其他人參加你的項目，你就必須拿出更多的統計數字；你必須展示你的項目的人性因素，這樣其他人就會感到拯救一個生命，對那些處在困境中的家庭到底意味著什麼。
i remember going to davos some years back and sitting on a global health panel that was discussing ways to save millions of lives. millions! think of the thrill of saving just one person’s life – then multiply that by millions. … yet this was the most boring panel i’ve ever been on – ever. so boring even i couldn’t bear it.
幾年前，我去瑞士達沃斯旁聽一個全球健康問題論壇，會議的內容有關於如何拯救幾百萬條生命。天哪，是幾百萬！想一想吧，拯救一個人的生命已經讓人何等激動，現在你要把這種激動再乘上幾百萬倍……但是，不幸的是，這是我參加過的最最乏味的論壇，乏味到我無法強迫自己聽下去。
what made that experience especially striking was that i had just come from an event where we were introducing version 13 of some piece of software, and we had people jumping and shouting with excitement. i love getting people excited about software – but why can’t we generate even more excitement for saving lives?
那次經歷之所以讓我難忘，是因為之前我們剛剛發布了一個軟體的第13個版本，我們讓觀眾激動得跳了起來，喊出了聲。我喜歡人們因為軟體而感到激動，那么我們為什麼不能夠讓人們因為能夠拯救生命而感到更加激動呢？
