When you are working hard, you don't have time for anything other than what you are doing in the scene and what the director wants.
Robert De NiroA lot of young actors have the idea that, "I've got to do this right. There's a right way to do this." But there's no right or wrong. There's only good and bad. And "bad" usually happens when you're trying too hard to do it right. There's a very broad spectrum of things that can inhibit you. The most important thing for actors - and not just actors, but everybody - is to feel loose enough to create what you want to create, and be free to try anything. To have choices.
Robert De NiroWhen you make a drama, you spend all day beating a guy to death with a hammer, or what have you. Or, you have to take a bite out of somebody's face. On the other hand, with a comedy, you yell at Billy Crystal for an hour, and you go home.
