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 encourage me to do so. Now I have changed great. In class，I am often the first one to stand up and answer questions even if I may take some mistakes. No pain，no gain. Now I am always brave enough overcome the difficulty in my heart and have changed in a lively girl. So my experience shows that we should not be afraid of losing face but only in this way can we make progresses.
