I want to study marketing

Today I had a big fight with my father. I am almost sure that I am going to leave home and move with my boyfriend if I want to be happy. My father’s problem is my future. He wants me to become a lawyer and all I want is study marketing, especially chiropractic marketing. He doesn’t approve. He wants me to become a lawyer because he is one and he believes that is the best job. I don’t like it and he doesn’t understand. That is why I am going to move and start studying chiropractic marketing.
