A: You look worried. What's the matter?
B: I'll have a ping-pong match against Mike tomorrow. I think I'll it because he is much better than me.
A: Don't worry too much. Let's play a game. Look, is this glass of milk half-full or half-empty?
B: Half-empty. What's the of it?
A: This game is used to test people's opinions. The opinions show people treat life in two different ways. I guess you don't often believe things will turn out well.
B: No, I don't. When I face challenges, I always feel nervous about what lies .
A: Perhaps you don't have a good of challenges. Why don't you think positively? I mean, look at the bright side.
B: But how?
A: If Mike beats you, don't be sad. Think about his strengths and your weaknesses,
. And the learn from him.
B: Maybe you're right. I need to be worried, but I don't know why I can't help worrying.
A: Well, worrying is not always bad. It warns you of risks, just like a fire alarm. However, the trouble is that sometimes it goes off there isn't a huge danger.
B: I see. So a half-full glass of milk means thinking positively. The game teaches me to the way I think. I'll learn to do it. Thanks.
A: Hope things work out.
