7. 猴子原則：猴子喜歡吃香蕉。第一個人走過來，扛了兩袋世界上最好的蘋果和桔子，猴子大怒，喝道：“你給我滾！”第二個人過來了，帶了兩袋世界上最好的蘋果，最好的桔子以及最好的香蕉，猴子在袋子里翻了半天，看到的都是蘋果和桔子，正準備發火，終于在袋子底下看到了香蕉，也就不發怒了，但是它對第二個人沒有任何感激之情。第三個人來了，一邊唱，一邊跳，兩只手里各拿著一支還沒有熟透的小香蕉，猴子一看，特別高興，撲過去迎接他的到來。猴子需要什么，你就給它什么。

The Monkey Principle: There was a monkey who liked to eat bananas. The first person who passed by was carrying a bag of the best apples in the world and a bag of the best oranges in the world. Enraged, the monkey screamed, “Get out of here!” The second person who passed by was also carrying a bag of the best apples in the world and a bag of the best oranges in the world. But the bags also contained the best bananas in the world. The monkey searched the bags, and when he could find nothing but apples and oranges, was about to lose his temper, when he suddenly discovered the bananas at the bottom of the bags. So he didn?t get angry, but he did not regard the second man with any friendliness. A third man passed by, singing and cavorting. In each hand he held a small, unripe banana. When the monkey saw the bananas he was delighted, and ran gleefully to welcome the third man. Don?t give the monkey what he doesn?t like.
