信息归纳

请阅读Jason在他的个人主页上写的一篇文章,根据所提供的信息,完成信息卡。

    Our words carry huge weight. They may influence people for years, and even for a lifetime. They provide them with courage to go on or one more reason to give up.

    When I was fourteen, my family moved to another city. Junior high was always a difficult time for me, and the move made my ninth-grade year even harder. I remember walking into the dining hall for the first time. The other kids had good friends with them, but I didn't know anyone. I felt lonely and went to the nearest seat after getting some food. The kids beside me looked at me up and down and then laughed. I could feel my face turning red at that moment. Then one of the Kids broke the ice. “Man! You have one BIG nose!” I felt hurt and didn't know what to say. I wanted to cry. But I managed a little smile---as if it didn't hurt me at all. But it did. From then on, I would often look at myself in the mirror. I studied the big nose closely. It seemed that I was just living for my nose. Thankfully, I grew out of this influence finally. But it really took me twenty years

    There is another thing that is kept deep in my mind. I remember going through a terrible business failure. I lost everything. I called my dad for help and he told me a lot about how to deal with the failure. What he said gave me a lot of courage and confidence(信心)to go on with my business.
