I'm totally new here and I'm not sure if this is where I'm supposed to post this but... talking about acting classes, I'm tryong to find a more professional school neaby my city cause I felt I wasn't learning much at the other one. My biggest problem is... getting into the character! I hear about all these people who actually feel like someone else, become someone else on the stage or whatever they are. Is that something that you get with lots of practice or what? I realy need to learn how to do that, though I'm pretty rookie with acting. Any advices?

Thanks a lot!
Lil.
