why the fuck am I worried for my future

so I'm still a teen but I'm worried and always overthinking what the fuck I will do when I grow up.. I'm thinking about how to get money the fastest, what kind of house do I want , how to become a good parent for my future child and other shit. but then I try to think back that I'm just a teenager and this shouldn't really stress me but for some reason I'm always thinking bout this and trying to like be ready when the moment comes or something idfk
