The web hosts a bevy of very informative articles in the acting world, and I have a few up my sleeve, one of them being Erin Cronican's acting blog. She's the founder and coach of The Actors' Enterprise and has been doing it for so long, that she has a sidebar to help you find the topics she's already dealt with. Have a question about the difference between agents and managers? She's covered it. Headshots? Been there, done that too, and all the information is super easy to find. She also has her own personal acting blog to follow her take on the whole acting world as well, but In New York! Oh, NYC! In case you didn't know, New York theatre is good. And LA theatre is usually quite bad, so our adventures, while similar, are still very very different.
In a recent column, she talks about establishing a fan base, and gives some pointers on how to do that. Fans help cheer you on, yes, but when your fans are also your close friends who offer you invaluable advice and support, well, it helps make your artistic endeavors seem like less of an uphill battle, or struggle, as it were.
Make friends with other actors. Befriend new actors and help cheerlead them along. Never see another actor as competition. That's now what good actors, heck, good PEOPLE do. Help, cheerlead, mentor. It will all come back to help you. I swear it.
