"The Meisner acting technique is a many layered approach that relies heavily on a practice known as emotional preparation. Named after Sanford Meisner, the Meisner technique began as a systematic study of the art of acting for theatre. Based on work done by Russian actor Constantine Stanislovski, Meisner created a hybrid technique that he felt was better suited to the American actor and American theatre. ...
Actors using the Meisner acting technique have the ability to immerse themselves in an emotional 'state' of the character before going onstage. Rather than pretending extreme frustration they must ARE extremely frustrated as they enter the scene. Furthermore, Meisner believed that any actor looking to exploit the Meisner acting technique does their homework by creating and developing a complete set of circumstances and a complete emotional landscape that is in tune with the deeper cravings, needs and emotions that have caused the character to be frustrated."

"[Sanford Meisner] said 'acting is the ability to live truthfully under the given imaginary circumstances' now he had worked on that sentence for 71 years, funny he didn't use the word 'talent'. He said it's an ability and an ability is a skill. And the cool thing about a skill is it's learnable."
