想成为出色的程序员，你必须承认你是个糟糕的程序员

To be a Great Programmer, you must admit that you are a Terrible Programmer
（想成为出色的程序员，你必须承认你是个糟糕的程序员）

然后他说，

"I am human, therefore I make mistakes. If I make mistakes, then I cannot assume that I will write code that has no mistakes. If I cannot write code that has no mistakes, then I must assume that mistakes are rampant within the code. If mistakes are rampant within the code, then I must find them. But because I make mistakes, then I must also assume that I make mistakes trying to identify the mistakes in the code. Therefore, I will seek the best support I can find in helping me find the mistakes in my code."
（我是人，因此我犯错。如果我犯错，那么我不能假定我写的代码不会有错。如果我不能写出没有错的代码，那么我必须假定代码内错误横行。如果代码内错误横行，那么我必须找到它们。但因为我犯错，那么我还必须假定在代码内试着找错时也会犯错。因此，我必须寻求我所能找到的最好的支持，来帮我在我的代码内找到错误。）
