Never lose yourself on the stage. Always act in your own person, as an artist. The moment you lose yourself on the stage marks the departure from truly living your part and the beginning of exaggerated false acting. Therefore, no matter how much you act, how many parts you take, you should never allow yourself any exception to the rule of using your own feelings. To break that rule is the equivalent of killing the person you are portraying, because you deprive him of a palpitating, living, human soul, which is the real source of life for a part.
