One day, a friend of mine told me a joke: A white cookie asked a black cookie why he was so black. The black cookie replied, “Because I don’t want to live in vain.” (In Chinese, “in vain” and “white” have the same pronunciation but different meanings.) After hearing this bad joke, in addition to feeling ridiculous, I couldn’t help but think: It is true that we are all unwilling to spend our lives in vain and we all want to live a life of value.
