You are the master of your environment. You've got your own head, your own mind. So once you figure out what you want for yourself, you have to create the proper environment to make sure you can live out all the things you want.
Your work isn't just to learn and say the lines. Your work is to figure out what the chatter in your brain is, that's going on under the lines. It doesn't matter whether you're speaking or not speaking because your mind is working the way your character's mind would work.
