Networking: The Birds of a Feather Rule.....

If you luck out and meet famous writers, artists, voice actors, animation directors, storyboard artists, production designers, and animators.....Don't expect a voice actor to be able to introduce you to designers.

The truth about anime in Japan and America is: Artists genuinely know people who do the same profession they do, mostly from working on certain projects together.

• Voice actors know other voice actors
• Producers know other producers
• Artists and designers know other artists and designers
• Writers and Directors know other writers and directors. 
• Japanese know other Japanese
• Americans know other Americans
• L.A. Workers know other L.A. workers
• Americans Living in Japan know other Americans Living in Japan

Makes enough sense...

There are exceptions, but mostly this is a rule of thumb. If you meet one celebrity in one field, they're genuinely only going to introduce you to people who work in the same field as them....
