One possible version： On the day of the competition，I saw so many people sitting in the lecture hall. This made me feel very nervous! I started to worry. Then I remembered what my teacher told me — close my eyes and take deep breaths. I did that and it made me feel much better. When my turn came，I gave my speech with confidence. I waited anxiously for the results，and when I heard that I was the first prize winner，I jumped up and down with joy. This experience taught me that being well-prepared is very important. And you should always have confidence in yourself!
