I cannot believe that the purpose of life is to be "happy." I think the purpose of life is to be useful, to be responsible, to be compassionate. It is, above all, to matter and to count, to stand for something, to have made some difference that you lived at all.

我不敢相信生活的目的就是“快乐”。我认为人生的目的是要做一个有用的人，要有责任感，要有同情心。最重要的是，重要的是要有意义，要有价值，要有意义，要让你的生活有所不同。
