What Career/degree to choose if you’re not smart??

Hello, I was okay at school and somehow was able to do running start( collage classes in high school) til now I’ve been doing my nursing prerequisites. But I’ve learned that I am not as smart as one needs to be in anything. I’m not good at math and I’m not good at science so I struggle at everything I do. What majors can I choose that will get me a stable job that pays about $80k? I know it’s probably a lot of money but please help!!!!!
