Get some friends to help you start an organisation at your school and get funded lots of money to paint yourself at every football and basketball game as your 'events' for the organisation.. hey, it worked for me!
I am huge fan of joing organisations, you meet like minded and interesting people to hang out with, plus you can add it as activities. Tutoring at local elem, middle or HS, or even entrylevel college courses.
Lots of stuff out there, just open your eyes!
