My dad was dying and I bought several books to take to him at the hospital. This was one of them. When I flew down to see him, the word was that he still had hope. Within thirty minutes of my arrival, we found it not to be true. I still read him this book, just as he used to read it to me. It was a joke for us during his last days. Even when he had break through pain and I wasn't allowed to give him more medicine, we'd read this and he'd squeeze my hand while he tried to get through just a little more time. Sometimes he told me the story to keep his mind focussed.
Before he died he told me to finish my degree. I told him it would be hard because I have a big family, so much going on-- and he smiled and said, "Let me tell you about a train that couldn't get over a mountain. It had great things on it, toys for the good boys and girls, milk for their dinners. It was hard to get this train loaded with good things over the mountain but there was one little engine. . ." Three months later I am in college and this little engine goes through my mind a lot. The story is one of my children's favorites and they don't know why I can't read it without crying!
This book appeals to everyone for different reasons, but the results are the same. An iron will allows us to overcome any obstacle!
