I'm in the 10th grade and i am trying to decide what to study in college. I am really good in physics, math, and chemistry. The thing is that i am very much interested in astronomy and stuff like quantum mechanics and string theory. A lot of people keep telling to study something more "practical" such as engineering(to find a better job) but i don't want to. Should i go for theoretical physics? Any and all opinions are appreciated. Thank you .
