As a very young singer, I was invited to the opera house in Berlin by the then-director of the opera house, Egon Seefehlner, and I had one opera to my name that I knew. He felt that there was a lot that I could learn there, which was very true, and I was so lucky to be able to have this opportunity. The thing that was happening is that I kept being offered operas that I knew that I wasn’t ready to sing, just from an experience point of view, as well as being 24 years old. So I was always asked to sing things that I thought, “Well no, I really don’t think I should sing that now. I need to sing that maybe in five years, or maybe in 10 years, but not right now. Couldn’t I please sing something else?” And that became a difficulty for me. And after being at the opera house for three years, and singing Elsa and Elisabeth — the Wagner roles that are not sort of the heavy Wagner roles — and then Mozart operas that suited my voice at the time, I was continually invited to sing things that I just felt I shouldn’t. So I took it upon myself to go to speak with the artistic director to say that I thought I should leave the opera house, and come back in some years when my maturity sort of chronologically would have caught up with the invitations that I was being offered. Of course, considering that he’d taken me into the opera house when I knew one role, he wasn’t all that happy. I thought he’d say, “Oh, what a smart girl. Oh yes, absolutely. That’s what we’ll do.” No, no. He was absolutely furious.

Well, I ran out of gas. You know, I got to be what, 93 at that time, or something like that. And it just – same reason I gave up teaching. I teach – I was – I taught every year from when I was 21 till 88 or 89, and there just came a period when your body said different things to you, and you should turn it over to somebody, just like I did at Berkshire.

I have never liked the word retirement. It doesn't feel like a modern word to me. I've been thinking of this as a transition, but I want to be sensitive about how I use that word, which means something very specific and important to a community of people. Maybe the best word to describe what I'm up to is evolution. I'm here to tell you that I'm evolving away from tennis, toward other things that are important to me.

I read that at a key fork in the road moment for me where I just sold CD Baby and had a ton of money. I was like, “What to do now?” And I read this book from this filthy rich old man being entirely honest, and I thought I should just learn from his experience. ... So if what I’m doing seems weird, it’s because I took his advice to heart and I’ve quit the game.

That’s an easy question. It was, of course, George Balanchine. He came from Russia via Europe and settled in America in 1933. He started a little company which was not very successful, so he had to start over and over again. Ultimately, he founded the New York City Ballet. I happened to be born at the right time, came to the right place, and had the fortune to audition for him, and work with him, because he is the genius of the century of ballet. I learned how to dance with him.

Well, I’ve had injuries, but I’d always get out on stage because I think the body is a wonderful thing, and you have to treat it with respect. We haven’t even reached our potential for what we can do as human beings. I went through a period where I had hip trouble. I thought it was just a typical pulled muscle, so I used liniment, and warmed up more than I thought was necessary, all the things we learn to do when you have a typical dance-related injury or sore muscle. Over the months, it didn’t go away. In fact, it got worse. Eventually I realized that I had a very serious problem, and it was the first time that dance had let me down. What had been my salvation and my security with my body was abandoning me. This was emotionally and physically devastating.

No, never. Strangely enough, being such a tomboy, and being so—as my mother says—spoiled as a child, once I started dancing and in a way growing up, I was not the spoiled brat or the rebellious child that I was when I really had no reason to be as a child. When you work, it’s a laboratory. The dance studio, when we were working together, was the place where you experiment. I’m not intimidated by failure or making a mistake, because you learn from those situations. You don’t learn from a situation where you do something well. You enjoy it and you give yourself credit, but you don’t really learn from that. You learn from trial and error, trial and error, all the time. When you fail, maybe you failed in that particular instance, but you have discovered something else. A lot of the ballets that we went on to do were built around mistakes that we had made in the classroom. So you never throw anything out. Rebelling takes up energy. As a dancer, you don’t have that kind of energy to throw away.

I think he was a great philosopher. He had a wonderful theory that you live in the “now,” which I think is important. Along with living in the moment, you also have to assume the responsibility that goes along with it, and you don’t take your position lightly. But it also means that you get the full value of the moment that you are living, so you don’t look back on your life and say, “If only I hadn’t wasted time, if only I had done this.” You do the best you can. It was wonderful to be able to go home after a performance, and think, well it wasn’t maybe so good, but it was the best I could be at that time.
