future job.. HELP

I'm a junior in high school and I really need to start figuring out what I want to do. I need some opinions and insight on which direction to go, so anything is helpful. I love health and life style. I love how the human body works and have currently taken an interest in being a yoga teacher, I really want to open my own studio one day. But at the same time I feel like I should Pursue a different career. I honestly want to go to a yoga school, but the closest one is hours away. Do I really need to go to a yoga school to teach when i live in such a small town? I'm confused!!
