The Butterfly Effect is based on a theory that was first presented back in 1863: That a butterfly could flap its wings, which would move molecules of air... which would move other molecules of air... which would move other molecules of air.. which could eventually start a hurricane on the other side of the world. Taken a step further, it follows that the decisions we make, both large and small, MATTER, and have a far-reaching "butterfly effect" not just on our lives, but on everyone - and everything - around us.In this beautiful and thought-provoking little book, Andy Andrews perfectly illustrates this butterfly effect, first with the story of a man named Joshua Lawrence Chamberlain, whose actions over 100 years ago greatly affect how we all live today. Chamberlain was a Colonel in the Union army, and the decisions that he made during just one battle literally changed the course of our country. Andrews then goes on to recount the contributions of another (connected to another, connected to another...): contributions that changed, and continue to change, the lives of billions of people. He challenges the readers to remember that we too serve a purpose, and that our actions are far greater reaching than we can even imagine. We are all connected, and just like the butterfly's wings, our most innocent decisions can affect the lives of countless others.This is truly a lovely book, both aesthetically and in its message. It is a book that encourages and a book that inspires.I received this book free from Thomas Nelson Publishers as part of their book review bloggers program.
