find a career

I’m in my second semester in college. It’s getting me nowhere while i’m spending lots of money on it. Each semester I spend about 1500 on books and tuition. So about a third of my income is going towards schooling i also have a car payment and rent along with a son and other things. I think next semester i will be changing my major to something i can get done faster istead of going to school for 5 or more year with no promising career. Im thinking dental assistant or ortho assistant but i think i would be going for just about the same thing.
