„I don't understand acting. Sometimes I only understand it while I'm doing it, and sometimes not even then. You cannot study acting. You can get new tools to use…, but you can't become something by studying, you just can't. You can become better. But some people can't even do that. They are best when they are very young because they are restless. When the restlessness settles, the acting goes. When acting goes for me, I'll just stop and do something else. I hope I always will get better and better, meaning bigger and bigger and more courageous and deeper and lighter and more flexible. But when it's time to go, it's time to go. There is no use trying to ride a wooden horse.“
— Nastassja Kinski
