　"If someone did you a favor -- something big, something you couldn't do on your won -- 　instead of paying it back, you paid it to three people... 　And the next day, they each paid it forward to three more... 　And the day after that, those 27 people each paid it forward to another three... 　And each day, everyone in turn paid it forward to 　three more people... 　... In two weeks, that comes to 4,782, 969 people... 　Have you heard?" Pay It Forward 如果每一天， 都可以把世界變得美麗一點、 把身邊的人變得快樂一點， 那是多好的一件事。
