Work (flying airliners)
Working out (seriously stay in shape)
I am amazed you are in 6th grade and know how to do long haul flights already. If I were you, while doing a long haul flight, buy aviation books and start learning how to fly in real life. Turn your hobby into a career (and while you study while flying, your parents will understand your passion for aviation). If you are in the United States, concider picking up the “Pilots handbook of Aeronautical knowledge” and the “airplane flying manual” both published by the FAA. You can download them for free off of the FAA’s website or buy them on Amazon or such. Good luck!
