     At the beginning of my 8:00 a.m. class one Monday at UNLV(拉斯维加斯内华达大学), 

I cheerfully asked my students how their weekend had been. One young man said that his

weekend had not been very good. The young man then proceeded to ask me why I always

seemed to be so cheerful.

     His question reminded me of something I'd read somewhere before: "Every morning when

you get up, you have a choice about how you want to approach life that day," I said to the

young man. "I choose to be cheerful."

     "Let me give you an example," I continued. "In addition to teaching here at UNLV, I also

teach out at the community college in Henderson. One day a few weeks ago I drove to

Henderson. I exited the freeway and turned onto College Drive. But just then my car died.

I tried to start it again, but the engine wouldn't turn over. So I put my flashers on, grabbed

my books, and marched down the road to the college."

     "As soon as I got there, the secretary in the Provost's office asked me what had happened.

'This is my lucky day', I replied, smiling."

     "Your car breaks down and today is your lucky day?" She was puzzled, "What do you

mean?"

     "I live seventeen miles from here. I replied. My car could have broken down anywhere

along the freeway. It didn't. Instead, it broke down in the perfect place: off the freeway, within

walking distance of here. I'm still able to teach my class, and I've been able to arrange for the

tow truck to meet me after class. If my car was meant to break down today, it couldn't have

been arranged in a more convenient fashion."
