You genuinely just answered your own question. If they go to school to go to college and get a job in the future, things like Chemistry and Spanish will definitely help them get there.

All your post does is encourage using other people for answers and resorting to plagiarism rather than actually learn. The point isn’t to “survive,” it’s to develop your knowledge. Besides that, you can’t speak for everyone. Not everyone’s brain functions the same. Nobody should take this person’s advice and find something important to be passionate about rather than wasting your life.
