'my desire to change the business world' BU Supplement need proofreading

Boston University: In no more than 250 words, please tell us why BU is a good fit for you and what specifically has led you to apply for admission.

I have experienced many things throughout my eighteen years of life. These had positive as well as negative impact on my high school career. Since I was a child I have moved around numerous times, I believe that this was a valuable experience for me because this provided me with an opportunity to experience and view different aspects of life. It seems that with the experiences I learned to incorporate new ideas and comprehend the value of difference. I thought Boston University would be the best place for me to use this strength because it is located in the heart of one of the most cultural and diverse cities in the world. Different cultures and religions in Boston University will further enhance my strength to incorporate new ideas and allow me to grasp many attributes that could only be learnt from meeting different people of different experience and background. The management exchange program and management internship program specifically led me to apply to BU. Through the exchange program I hope to learn how business management is done in other counties and try to incorporate and put together the best business management system for America. The financial crisis our nation faced fueled my desire to change the business world and to prevent it from happening again. I believe Boston University will be the first step toward that goal.
