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.
A sense of responsibility is the mark of a noble character.
小人反复无常,不可深交。  
在电影制作中你必须无所畏惧。你必须冒险,不要害怕失败。
