" Whatever we do makes a difference," Eithnie said. "Doesn't matter how small our efforts might seem to us, it'll still make a difference."
"But what about all the people who don't do anything, or who don't do anything positive? Won't their actions, or lack of actions, cancel out the good we're trying to do?"
"I guess I'm thinking that it's also like dominoes. You know how when you knock one over, more and more fall, one after the other, until they all come down? (Edward) Lorenz's theory assures me that what I do Will make a difference, I can't tell how, I can't predict when or where, but it will effect a change. I just have to concentrate on maintaining that effort so that one day all the dominoes will come down in the right way. "
