Recently I took part in an English speech contest and successfully went into the final. That day, I thought I had done a good job. At that moment I even had a strong feeling of being the champion. But my dream was soon shattered when my final score was announced. I stood in the hall, feeling empty-minded and puzzled. My memory went back to when I was in junior middle school. I took part in a similar speech contest. I was too proud of myself. I was not well prepared, so it ended up as a total failure. But this time should be different! I had spent a lot of time tailoring each word. Why was it all in vain and I had to be a loser again? Very frustrated, I swore not to take part in this kind of competition again.
I was just about to leave when a well-known TV host suddenly said to me he did appreciate my speech. On hearing this, I was filled with mixed feelings---partly surprised, partly excited, partly sad, but there was one thing I am certain about---I did feel something warm and comforting floating inside my body. I never knew a few words and a kind smile could be so inspiring that I suddenly realized that frustration, sorrow, happiness and inspiration are treasures to make life more meaningful. It is these elements that make life real.
