When I was in high school I did....
theatre company (I was an officer senior year, too lol)
National Honor Society
newspaper
television station
Spanish club
photography club
yearbook
And now that I'm in college:
newspaper (yeah, I'm a journalism major)
Lambda Pi Eta (national communications honor society)
editor/reporter/designer for campus magazine (just this semester - it's for a class so the staff changes each semester)
Entertainment Unlimited (club that does different on and off campus trips and activities)
Pride Guide (tour guide...)
and last year I wrote for Nassau News Live (a community-based news website that's run here at school - but only because I had to do it for a class - I refuse to write for it this year LOL)
And I work on campus in the Admissions office (we process the mail and send out mail and stuff packets... it's not great but it pays decently... especially days like today where I sat on my laptop for 2 and a half hours...)
