I began collecting synonyms for the word "failure" mentioned in the interview, and I found more than 20: mistake, error, false start, flop, loss, miss, stumble, botch, bungle, --but not failure.

在访谈中，他们用别的同义词代替“失败”这个词，这些同义词有20多个，如过失、错误、起步失误、栽了、亏了、错失、弄错、弄糟、搞砸（砸锅）等等，但都不是“失败”。

要是你养不好孩子，我想其它的事情你也不会很看重。
