研究7法则。如果你愿意进入七个层次，你就能找到任何东西。如果你问的第一个信源不知道答案，就问他们你应该问谁，以此类推。如果你愿意问到第七个，你几乎总是能得到答案。
Rule of 7 in research. You can find out anything if you are willing to go seven levels. If the first source you ask doesn’t know， ask them who you should ask next， and so on down the line. If you are willing to go to the 7th source， you’ll almost always get your answer.
