New school, what should I do? (I'll be a junior)?

I'll be a junior in highschool this year and I might be moving. I don't want to be the same person I was at my old school, I've gone to school with the same people my whole life, so what should I do? I dance at a studio for 6 years, and I'm on student council this year. I love to sing too and theaters always fun but i want to be more sporty and get alot of new friends so any suggestions? Please and Thank you! xoxoxo
