The main idea of the story is about kindness, I reckon. The idea of helping others without expecting something in return and hope that the person, would do the same thing to another person. And that another person, would do the same thing to anyone else and it all would eventually create this sort of 'kindness chain'. Hence 'pay it forward'.
This is very motivating and thought-provoking although the 'positive energy' that it gave me didn't last much long but it still did happen to give me such a positive energy so well it's good.. Gotta warn you first though that it's a major tearjerker.. Like it hit you right through your heart and makes you feel the pain just like in the movie.......
Okay I exaggerated it a little bit but it IS a sad and a very motivating movie.
