You could drop a few thousand dollars into a pricey camera, save up, move to Hollywood and try to keep tabs on all the celebs whereabouts. get a fast car and a crew. Drive around and if you see celebs snap photos and sell them to a magazine company or news paper. Hopefully your freelance can get you in the door.
as well as studying journalism I would also study photography because you need some photography skills and the more skills you have the more people will want to employ you
Get a canon EOS 1Ds (or comparable camera), with a telephoto lens, then take photos of well known people, and sell them to a magazine
You study Journalism, work very hard and hopefully you'll get to photograph celebrities.
