Why my major?

So in English class, we have a project on our profession, or our major. I'm majoring in Dental Hygiene, so it's difficult to be able to interview someone who is in that profession, especially when I don't know anyone in it. So I started to ask myself why am I majoring in this major? What's so great about it, that it's something I'm studying. Then I realize...my parents. My parents were the one who decided my major, and my career for my future. It's not so great that my parents are the ones that determine my future, but for now, I don't really mind. I don't mind only because I honestly don't have a passion or desire in something. When I grew up, I always wanted to be a lawyer. But thinking about that now, there's no way I can be that. I'm no where near being good at arguing to win a case, nor is my vocabulary so great. So that's not possible. So I guess being a dental hygienist isn't so bad. Although, it's only my backup. According to my parents, I'm suppose to continue in the dental field and become a dentist right after. I don't know about being in peoples' mouths all day, but it shouldn't be too bad after you get used to it? It's not so great of a job, but the pay is good ;)
