My rich experience and long time in the dance team qualified me for the top class, which I felt was a right 5 . However, when the class began I 6 that I did not know as much as I thought I did. My over-confidence 7 me to fall flat on my face. It seemed as if every girl in the class could perform challenging jumps, leaps and other 8 tricks except me. All of that “former experience” got me nowhere. Because of that I became discouraged and wanted to 9 immediately. My frustration kept me from doing my best. As a result the final performance was nothing but embarrassing. On the stage I 10 forgot how to dance and most of the time I just stood there, looking 11 , while the other girls performed like professionals. How embarrassing it was! From this experience I 12 that people are sometimes not as good at something as they think they are; there is always someone out there that can do it 13 than you. I also learned that there is always room for 14 , and I should do my best whatever the situation is. I know if I do not try my best, I will 15 even before I begin. | ||||
