How do I know if I'm choosing the right career?

So I just graduated high school a little over a month ago and I'm deciding what I should major in, in college. I was so stuck on becoming a nurse practitioner, but I'm also very interested in becoming an accountant because I'm amazing at mathematics. I like nursing because I love helping people, but I like the idea of being an accountant because I love math. I'm stuck. How do I know if I'm choosing the right career path for me?
