What do you want to be when you grow up?

I don't know how people decide on their future careers. Is it that something in their life happens, or is it that people just except you to be a particular person and thats what you end up becoming. I'm glad that my parents don't pressure me to a particular course, they have left the decision on me. As long as I have a good career, they don't mind if I'm a lawyer, or a doctor, or whatever. I was just thinking what I would actually enjoy doing. A career that I won't get bored of throughout my whole life. Maybe its not the right time to think of a career, maybe I should just finish Sophomore year. So I'll think later about my future career.
