Many people think this film is mainly about passing love and studying to love,but I think there is another way to explain this film ----- about changes. The boy, Travelor , be encouraged to take some steps to change our world by his teacher . As a careful boy ,he really do so (He tries his best to make the world better ).He set up a project called "pay it forward" and it's a wonderful but a little crazy idea .In the class he introduces the project to his classmates but it seems that almost all the people doubt it . In the end he carries the project on .But actually he doesn't think it works little by little .when a man helped by him eats the drug again ,he lost all his heart . To his great superise, in the day of his birthday a reporter comes to his house wanting to interview him . it's then that he finally kown his project is supported by many people using action in many cities. his last words move me into tears .we all really need to be brave and to think or do what it is generally thought it is unlikely to accomplish. Most of us may get used to the lives we lead for ages .But to make our live more colorful and fruitful ,we need to learn to change .it may seems difficult to us ,but we can draw many lesson from it .we can make us better . So ready to change the world ?
