I would take flying lessons at the closest place to get your Private while in high school if you can or wait until the summer after.
As you get your Private you will learn much more about options from other students and the CFI's at your school.
Then next summer, start the process of looking around. You should ALWAYS have a backup plan for a career when getting into ANY career not just aviation. But in aviation I think its even more critical because of health requirements in order to fly.
