I couldn't believe my ears when I heard my name calling. I was chosen to play the leading role in the play, that was my dream. As a shy and thin girl, I used to be quite afraid of speaking in the public. But my parents and teachers always encouraged me to do so. Now I have changed great. I am always brave enough to overcome the difficulty in my heart. So my experience shows that we should not be afraid of losing face and only in this way can we make progresses.
