Scholarship / Doctor, biology: educational, career goals, reason for choosing your major [2]

prompt: Please state educational and career goals and the reason for choosing your
major

For as long as I can remember, I have wanted to become a doctor, someone capable of preventing and alleviating pain and suffering in others. As a child, I naively thought that I could just grow up and become a doctor. My eldest brother also wanted to be a doctor so when he went away to college to major in Biology I was thoroughly confused and surprised. I began to wonder what I would major in when I went to my 4-year university. Every break my brother would come home with stories upon stories of all the amazing things he was learning and experiments he was performing. I realized that I wanted to follow in his footsteps and major in Biology. To me, Biology is the perfect major before attending Medical School. After obtaining my bachelor's degree in a field close to medicine, I plan to attend a refined medical program. The knowledge that I will acquire during the next four years will undoubtedly help me throughout medical school.

My goal is to graduate summa cum laude with my bachelor's degree in Biology in the hopes of of attending a renowned medical program to become a Doctor of Medicine. Within my career, I would like to open up my own practice. I would love to call my own shots so I can make my patients experience in my office pleasant. Seeing people cured and healthy in the shortest amount of time possible makes me feel accomplished. I love brightening another person's day. I know that being a doctor with a background in Biology would be the best means to live the life I have always wanted.

ANY help/advice would be greatly appreciated. even for grammatical errors. PLEASE HELP!
