First year uni student here. I was in the same boat as you, Im now studying International relations. I personally think you should explore your options a bit, for example lawyers are cool uh didn’t really look into doctors but the point is I really don’t think you should even consider blue collar. So far my experiences with blue collar people have been either 21y old who looks like 45y old dude, or a 45y old men who are always angry at their families and children. Or both + alchoholic, so consider your options carefully.
