Don't know what to do

[Celtics]

I have this semester and one more until I'm out of high school and have no idea what I want to do with my life. I was thinking being a vet but at least 8 years of school then 1-3 years of internships or whatever you call it, is to much for me. I'm an introvert and being a vet would be one of the only public speaking jobs I would enjoy. Money is the biggest issue to me and I want something that I don't have to worry about paying bills and knowing that money won't be a problem.
Any advice, I wouldn't want to go over a bachelors degree by the way, I just don't know what to do.
