It feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War III. All these because I don’t plan to be a doctor. And much to her sadness, I don’t want to do any job related(和…相关) to science, either. In fact, when I said that I planned to major(主修) in English and communications, Her heart was broken.

“Why can’t you be like my friend’s son?” she bemoans(抱怨) all the time. Her friend’s son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer. I can’t be like him. He is Mr. Perfect. I’m the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名声) or salary(薪水).

I understand why my mother is worried about my future major. I’ve seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6.30 a.m. and usually comes home around 5 p.m. or even 6 p.m. However, I want her to know that by becoming a doctor, it doesn’t mean I’ll be successful. I’d rather follow my dreams and create my own future.
