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.
