求翻译：读了这篇文章，我深深地体会到，只有乐观，积极，微笑，才会使我们有精神，也只有有精神，我们才会拥有健康。病痛，往往只有在我们心里。心里有病，才是最折磨人的病。是什么意思？

Read this article, I deeply appreciate only optimistic, positive, smiling, will enable us to have spirit, and only the spirit, we will have a healthy. Pain, often only in our hearts. Heart illness is the most unfortunate disease.
