Not all of us knew what we wanted to do in middle school.
I thought through middle school and high school that I wanted to be a professional musician, but after one year of that in college I decided to study chemistry, which I wouldn't have known I liked had I not been forced to take it in high school, nor would I be able to study it had I not been forced to go through trigonometry and advanced algebra.
tl;dr You're required to study different subjects in school because there can only be so many firemen and veterinarians in the world.
