If I could do what I love most, I would cook for my mother, travel with her and give her daily massages. My mom has spent her childhood caring for her siblings. She expected her adult years to be more relaxing, but her children ultimately limited her leisure time. My mom worked all her life and sacrificed her happiness in return for mine. In order for me to help others and change the world, I must first improve myself. I live in a society where people are competitive whether regarding school or work. Therefore, I must be a rival as well, but there is a downside to that. By being competitive in school, I spend most of my time doing homework and volunteering to prove to my competitors that I am a hardworking and helpful person. In addition, medical schools prefer diligent students. While I am striving for my goal of becoming a doctor, I am unhappy that I spend little time with my mother. I wish I can repay my mother for all the time and effort she has devoted to me, but it is challenging to care for her when I am fighting a war at school. Essentially, I feel that this essay could be a small part of my repayment for my mother. I want her to know that she is my world and that I will put all my effort into my education so that I can help patients leave this earth with minimal pain.
