Chapter 3: Only the Size of your Heart Matters. I’m really enjoying the chapters because they are so practical to our lives, they aren’t long, and once you read the chapter you can start living out the lessons right away! There isn’t any time wondering what the chapter was about, or how it could apply to your life. I think that the earlier we learn this lesson in our lives, the better off we will be! That’s one of the lessons that I try to teach my students.
