It's pretty common for someone your age (and mine too, I guess) to be indecisive about the future. Just keep an open mind that there are literally thousands of professions out there and the number is growing everyday. Don't limit yourself to just one or two things you want to do.
Hopefully, but since I am considering being a architect I need to learn Art and Modern Technology which I hate! But I have more of a passion of becoming a doctor of some sort or maybe a scientist or a lawyer - OR a dentist. Haha; I know, I want to be a lot of things. XD
