Optimism and pessimism are both powerful forces. Each of us must choose which we want to ______ our future and our expectations. We can choose to laugh or cry, bless or ______. It’s our decision: from which perspective do we want to view life? Will we look up in ______ or down in desperation?

I believe in the upward look. I choose to ______ the positive and skip right over the negative.

An optimistic attitude is not a luxury(奢侈品); it’s a(n) ______. The way you look at life will determine how you feel, how you perform, and how well you will get along with other people. ______, negative thoughts, attitudes, and expectations ______ themselves; they become a self-fulfilling prophecy (预言). Pessimism creates a dark place where no one wants to live.

Years ago, I drove into a service station to get some gas. It was a beautiful day, and I was feeling great. As I walked into the station to pay for the gas, the attendant said to me, “How do you feel?” That seemed like a(n) ______ question, but I felt fine and told him so. “You don’t look well,” he replied. This ______ me completely by surprise. A little ______ confidently, I told him that I had ______ felt better. Without hesitation, he continued to tell me how bad I looked and that my skin appeared yellow.

By the time I left the service station, I was feeling a little ______. About a block away, I ______ over to the side of the road to look at my face in the mirror. How did I feel? Was I affected with jaundice(黄疸)? Was everything all right? By the time I got home, I was beginning to feel a little nauseous(恶心). Did I have a bad liver? Had I ______ some rare disease?

On another beautiful day, when I went into that gas station, feeling _____ again, I figured out what had happened. The place had recently been painted a bright, distasteful ______, and the light reflecting ______ the walls made everyone inside look as though they had hepatitis(肝炎)! I wondered how many other folks had ______ the way I did. I had let one short conversation with a total ______ change my attitude for an entire day. He told me I looked sick, and before long, I was actually feeling sick. That single ______ observation had a great effect on the way I felt and acted.
