Apply the acting method

After learning about those famous directors and actors, I think one thing that I really need to use in my acting is to put myself in the scene and respond to other characters' actions truthfully instead of just remember the lines. For example, I act Juliet, and I need to think of that I am Juliet. When Romeo leaves me, I need to recall my own experiecnes about saying goodbye to someone I love, so that I can express my true emotions out to make my acting seems real. Also, I need to put my emotions into actions, in order to tell audiences what I am thinking and what I am feeling right now. And I also need to understand the character fully to figure out what causes those responding emotions, which I mean is the historical pasts of the character.
