     I sat at my seat waiting for the school paper to be passed around. I waited anxiously, knowing that

once I received it I would know how good a writer I really am.

     When the paper arrived at my classroom, I nearly knocked down five of my classmates to get to the

first paper. With a school paper in my hands, I returned to my seat. About a month earlier, I had handed

in one of, what I believed to be, my best stories. I named it Symbol of Success. The head of the English

Department at my school, Professor Cullen had said that she would include some reviews of students'

stories in the latest school paper. Professor Cullen was known for her rough criticism. Impressing her

was very hard but I wanted to be the first to do so.

     I sat at the edge of my seat as I read through the other story reviews. There wasn't one story that got

more than three stars .I became calm and wasn't anxious to know my review. It was long after that I

heard someone shout out "Five stars?! Seriously !" from behind me. I turned around and saw the

shocked expression of Gene's face, "Peter, your story got five stars!" I couldn't believe what I was

hearing. I turned my attention back to my story and saw the five stars at the end of the review that I had

not read yet. I looked through the review written by Professor Cullen. She wrote that I had a gift for

story writing.

     I was proud that I achieved what I thought was impossible .For so long I believed I wasn't as good as

I thought I was and that my talent was not enough to cover up my lack of wring skills .But this review

proved that I was truly a good writer and that there was a future ahead of me in the field of fiction writing. The review and the five stars meant the world of me. Those five stars became the symbol of my success.
