"Be yourself; everyone else is already taken" (Oscar Wilde). If you don't go after what you want you will never have it. Ever since I can remember I was a shy girl who let life go past her. I never fought for what I wanted or cared about and I hated that about myself. I seem to exist only to please my family and friends. When I was in 10th grade my grandfather died and that had a big impact on me. I realized that I was living my life for other people, and that I needed to stop pleasing everyone else and focus on myself for a change. I started to find my identity; who I was, what I liked and what I wanted to say. I started volunteering at hospitals where learned that I really like hospitals and watching doctors do what they do. For example I was so captivated by a doctor who saved a dying patient life. I also read to kids at libraries and organized fundraisers for starving children in Somalia. Now I am a senior in highschool and I am proud of the person I have grown to become. I am not that shy naive girl any more. Attending the U of chicago will enable me to fulfill my potential by developing my peronal interest. This university will provide me with an environment in which I can develop because University of Chicago is a place which respects my personal ideas, values and beliefs.
