A good studio can be one of the hardest things in and when you are first starting out as an actor. It is a place where you can go to both learn and hone and your craft. And think of it as a place where you can build at any time during the day or night that you can talk to other actors who may have either the same experiences or the same problems that you may be having right now.
This could be a process of finding a good acting studio that may take a bit. The reason for this is that each acting studio may have different things that you would like in studio in different ways. No two studios will be ever being the same; you just have to find the one that works for you. In a way it is kind of like trying to buy a car, you just have to find the one that is right for you. It is not necessarily something that you walk into it is more something that you feel deep when you see or feel it.
It is a good idea to an acting classes through the acting studio that you have signed in with, therefore you can get to know the people who are teaching at the school of which you have signed up to. It is also a good idea to walk around the acting school to get a feel for the place to understand its history and the history of those that have studied there before you did, maybe even draw some inspiration from them as actors and their talent.
Be sure also to only take the classes that you are comfortable with. the reason for this being that you do not want to rush into something so so or to intense to fast. this could turn you off to being an actor an no one wants to put theirs dreams on hold due to a bad expeience. Also, be sure to only take as many classes as you can afford. Acting classes although not being cheap are also no good to you if you can only afford one every years or so. So shop around and find a school that is completely affordable for you as well. This can really be a benefit to you and also to your wallet.
Also be sure to talk to at least some of the speech teachers as well as the coaches. Get a feel for them and the type of people they are and the classes that they run. It should be pretty easy from there to find a school that you like enough to study at or comfortable enough to go to on a regualr basis to get tips and work on your craft as an actor. Don't be or get discouraged about how things go your first few times you go, keep with it and eventually you will succeed at whatever you put your mind to.
