My dream was      . By the time I was sixteen, I could throw a ninety-mile-per- hour baseball and      anything that moved on the field. I was also      : my high school coach was John, who not only      me, but also taught me how to believe in myself. He      me the difference between having a dream and showing conviction(信念).

You can’t afford to waste them.”I stood before him with my head      , trying to think of the      that would explain to him why my dream of buying my mom a house and having money in my pocket was worth facing his      in me.
