nothing else I like to do is very realistic. I don't really enjoy math, but I am extremly good at it. I'll get an advanced high school diploma, and probably get into a good college. But honestly, I'd rather live under a bridge doing something I enjoy than make loads of cash doing something I hate. I suppose I could just quit that job after a while, but it seems kind of a waste.
This is such a very, very young thing to say.
Let me guess: you live with your parents. They make your meals, wash your clothes, pay for medical and dental bills, shop for food, buy you clothes. You're frustrated, looking at the world and realizing that people spend most of their lives doing things they don't particularly enjoy. You don't want to spend your life like that. But the truth is, you have no idea how much the "live under a bridge alternative" is going to cost you.
So figure it out. See how many things are paid for (answer: everything) from day to day, and notice what people who live under a bridge really live like. Don't imagine you'll be any different.
Making a living writing novels is like winning the lottery, or being a rock star: you can't depend on it. And that's not making it rich: that's living as if you were working minimum wage. DON'T think you'll just get by somehow. That is a fiction.
And talk to your guidance counselor. It's their job to help you think of possible futures that might not occur to you. Figure out what things you like to do and what you don't, and expand your idea of "adult work" from the, like, five careers they teach you when you're in elementary school. Don't limit your options. Graduate, go to college, graduate some more.
Take some creative writing classes as electives and develop a routine of logging significant hours writing every day, because what really divides published and unpublished authors isn't skill or imagination, it's discipline. There will be days when you hate writing as much as you hate anything, but if you shy away from things that are grindy and unpleasant, writing will be as beyond you as everything else.
