"31 ways to change the world" taught me so many new things. I always thought that to make a change you need to be big or have a group. "31 way to change the world" showed me it doesn't matter how small the action is, little things make a big difference. I loved this book. My favorite part was learning some sign language. I also loved action #4 and action #31. I believe that "31 ways to change the world" is a excellent book for any age category.
