I don't want to go to college, why don't my parents understand me?

I will graduate high school, for sure. I repeat I am NOT dropping out of high school, it sucks but I'm sticking with it for a couple more years! I just don't want to go to college, there is nothing I want to do, nothing, I never had anything I wanted to do even as a kid. I mean I'd love to be an actress (and I think I'm pretty good at acting) but I know that's impossible. I'm fine with working at an office doing computer work or at with my aunt as a telemarketer. No one in my family went to college, yet we have Plently of money, huge house, nice cars and electronics. Why don't they understand I don't need college to be okay in life?
