In The Butterfly Effect: How Your Life Matters, Andy Andrews presents inspiring stories of influence. The book presents two extended stories of how one person through the midst of ordinary life can influence another. The first chain of influence was Joshua Lawrence Chamberlin, who stood with his union army in the battle of Gettysburg despite the odds. His decision to stand ground and fight led to a victory for the Union in a battle that helped to end the Civil War and save America from being divided in two. The second story shows how the chain of influence lead Norman Borlaug to create a form of disease resistant corn, which saved the lives of many people. Norman was influenced by many others through the midst of ordinary life who helped to mold him into the person he became. Andrews employs these stories to pose the question that stands at the heart of the book: “And how far forward would we need to go in your life to show the difference you make?” He continues with his challenge to his readers to step up and make a difference in the lives of others by stating: “There are generations yet unborn whose very lives will be shifted and shaped by the moves you make and the actions you take today. And tomorrow. And the next day. And the next.” The Butterfly Effect is a challenge to remember that “every single thing that you do matters.” Andy Andrews presents a very inspiring book to encourage readers to live to make an impact on others. My only hesitation is that I read this entire book in about 15 minutes and with a $15 price tag this might be worth taking a few minutes to read in your local bookstore rather than purchasing it.
