I live in a developing country and everything is focused in applicability: maths and languages courses are too much about applied knowledge, never seen as pure areas of study. The reason why I fell in love with maths and languages in the first place was by overanalyzing things that have no real impact in the world: I liked that they were beautiful on their own, with no need to ever be used. And the prospects for me are really negative from this point on, because I feel like every college I go to and every job available for me will be quite the opposite of that. I wish I lived in the US or Europe where pure sciences actually exist, but I don't, and I can't afford to go these places. I feel like there's nothing I want to do with the rest of my life, and yet my parents say I have to choose soon because I gotta make money somehow.
i think you will still get a chance to do many things with your life, besides the things you do for employment. Sure, make some decisions on that now, but just make the best decision you can, based on the information you have. even if if you don't have all the information. Because you are obviously still missing at least half of the information. most people are. but you will find a lot of that information along the way. And either one you choose, you'll probably learn something.  and also keep in mind that some of the most powerful things to be learned, may come from outside the 'curriculum'
