I had been playing hockey (冰球)for about 10 years, I was always the one sitting at the end of the bench, and 26 got into a game.I went to all the 27   and showed up even when itwas so 28 that your ‘breath froze’ and whenplayers    had decided to stay home. I feltI had   29   enough and thought of quitting”
I finally decided to 30 the news to my mom that I was leaving the team. My mom may have looked like a tiny and quiet lady but on 31 my words, she said, “Remember, ‘A quitter never wins and a winner never quits.’ Your mother didn’t raise 32 , so think about yourself in a 33 way and see yourself as a winner!” So I worked harder than ever at getting in better shape, 34 my shot accuracy and changing my 35 .
Once in a match, we 36 our first game badly. What’s worse, one of our best players got hurt. I was sitting at my 37 place, at the end of the bench, when the coach came over and told me I was going 38 . I was nervous, excited and terrified all at the same time.
The opposing team was fast and I had to admit I was a little 39 .  But my mom’s words   40 out in my head like a church bell. Instead of being afraid, I was “pumped” and I very quickly found that all my 41 work was paying off.  I was as fast a skater as anyone else on the ice, and I seemed to get the   42  to score. The crowd went quiet. All the time I spent on the ice when everyone had gone home had 43 me for this moment.
Won! I won!
The lesson I learned from my mom’s 44 has stayed with me over the years. I hear them whenever I am faced with a challenge, or whenever I 45 myself.
