I want to make the most out of highschool, what things should I get involved in?

If you'd like the greatest highschool experience, I'd suggest joining sports teams if you're athletic or even if you just enjoy sports. If you aren't the sporty type I think it would be a good idea to join various groups or clubs such as student council or maybe the art club. These are great places to socialize and meet new friends who can help make your highschool experience the absolute greatest it can be.
