Cause and Effect

Have you heard that butterfly in the Amazon effect? It has originated from that a butterfly flapping it's wings in one area of the world, causing a tornado or some such weather event to occur in another remote area of the world. I think that It means extravagant results could be caused by a small thing.

Also, These days, I have read a novel, "Pay it Forward". The novel's story is how one child who believe in the goodness of human nature chages the world. we can infer the relationship between cause and effect from the novel.

I found out a common thing from the novel and the butterfly effect's theory. It is that even though something is an unimportant thing, we should not ignore it because it could make important things and result. Therefore, I think that everything we have is able to become important and strong result in some moment. In other words, I think there is no useless things in our lives.
