An optimistic attitude is not a luxury; it’s a necessity. The way you look at life will determine how you     , how you perform, and how well you will get along with other people.     , pessimism creates a sad and hopeless place where no one wants to live.     thoughts, attitudes, and expectations feed on themselves.

Years ago, I     into a service station to get some gas. It was a    day, and I was feeling great. As I walked into the station to pay for the gas, the attendant said to me, “You don’t look well.” This took me completely by     . A little less confidently, I told him that I had never felt better. Without hesitation, he continued to tell me how bad I looked and that my skin appeared       .

By the time I left the service station, I was feeling a little     . About a block away, I pulled over to the side of the road to look at my face in the mirror. How did I feel? Did I look that     ? Was everything all right? By the time I got home, I was beginning to feel a little     . Had I picked up some rare disease?

The next time I went into that gas station, feeling     again, I figured out what had happened. The place had recently been painted a bright but disgusting yellow, and the light reflecting off the walls made everyone inside     as though they had hepatitis(肝炎)! I wondered how many other folks had reacted the way I did. I had let one short    with a total stranger change my     for an entire day. He told me I looked sick, and before long, I was actually feeling sick. That single negative observation had a(n)     effect on the way I felt and acted.
