First, get a library card. You're going to have a LOT of free time on your hands. Trust me. Those free movie rentals (at most libraries) will save your life.
Second, audition for everything - student films, commercials, random foreign TV shows that no one you know will every possibly in a million years see on some obscure cable channel that is only available in 4 zip codes and never ever let you live down once they have seen the depths to which you have stooped.
Third, try to interact with celebrities in any way possible. Walk past them in coffe shops, compliment them on recent awards won when you're volunteering at special events in Beverly Hills, apply for jobs in their ultra-hip trendy niche shops.
Fourth, develop a fascination for people watching. The crazies on the beach who think they can get away with that little clothing, but they really can't (Not that anybody can, but it's a definite negative for those folks.). The hopeless, yet adorable library volunteers who dress like old people, but not because they're old, and not in an I-meant-to-do-this-because-it's-vintage way. The people walking along Santa Monica Blvd, or Sunset Blvd, or Hollywood Blvd (just pick a Blvd) who are trying WAY too hard. The girl who thinks it's a good idea to wear
Lastly, get snacks. Lots of snacks. Share them, even. In fact, bring some my way.
