This edition of Andy Andrews' "The Butterfly Effect" turns the author's well-known speech into a delightful gift book.Andrews begins with Andrew Lorenz' butterfly effect theory and proceeds to demonstrate its accuracy via actions of such historical figures as George Washington Carver, Joshua Lawrence Chamberlain and many others. He looks at how their actions affected their contemporaries, and how their actions continue to affect us today -- many years after the fact.I found Andrews' little book to be thought-provoking and inspiring. The idea that all of us matter in ways that we don't even know is one that I believe should be taught early on; you never know when your kindness to another person will make a world of difference to them.Highly recommended.
