i don't know what i wanna do

i'm trying to figure out what i wanna do for a career still and "medical assistant" just came across my mind. so i looked up what medical assistants all do and everything that they do seems too secondary to doctors, i don't think that i would want to be that secondary to a doctor. i think that i looked this up before and said the same thing. i don't want to get to be 50 and still unemployed and/or still deciding on a career field. i told myself that i'd work on walking and then think about my career field but i hate how people still expect me to be taking college courses.
