柳波默斯基给幸福下了一个实用的定义，认为幸福就是指快乐而又满足的人生。有了这个定义，就可以给总体幸福提供必要的感觉和判断依据。

Lyubomirsky's working definition of happiness — "a joyful, contented life" — gets at both the feelings and judgments necessary for overall happiness.

我指的快乐是，当一个人可以对着自己说：“我是一个真正快乐的人，我再也不求什么。”

I'm talking about the kind of happy when you can say to yourself, "I am truly a happy person, there is nothing more I'll ever need."
