Years ago I worked at a factory in a small county. Every day I got up very early and often did much extra work at night. I was so tired and exhausted. My whole life was hopeless. Then one day I read the following article from a magazine:

"A woman went to live with her husband in camp on the Mojave Desert during the war. She simply hated the place: the heat was almost un-bearable, 125 degrees in the shade, the wind blew incessantly, and there was sand everywhere. Finally, in desperation (不顾一切地) she wrote her parents in Ohio that she couldn't stand it another minute and was coming home.

Quickly came the reply by airmail from her father——just two lines:

"Two men looked out from prison bars. One saw the mud, the other saw stars."

The daughter did some real thinking, not only with the intellect (思维) but also with her heart. She decided to stick to her post.

She made friends with the natives, learned to love the country, and eventually wrote a book about it.

The desert hadn't changed, but her attitude had. Because she listened with her heart  to the words her father sent, a whole new world opened up to her.

A change of attitude could change everything.

After reading the article, I was deep in thought (陷入沉思)…
