I realized I wasn’t sounding as good as my reputation was, so I wanted to kind of get to that point where I wouldn’t be ashamed to go on the bandstand, which happened to me one time on a job I was playing with… Elvin Jones, at that time, was the drummer playing with me. We used to go around, had a big sign, “Sonny Rollins is coming to town,” everybody was there, but I didn’t sound good, and I knew I wasn’t playing up to what I should be. So I said, “Okay, I am getting out of here. I am going to go and woodshed,” as they say, and get myself together.

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.

No, I think they were two totally different careers, because when I was acting, I was always impersonating different people, so it was never me—it was never myself. When I started to sing, I suddenly felt naked. I mean, I knew that was going to happen, because that’s the reason why I couldn’t do it before—when I was a teenager, I just couldn’t play in front of anyone at all—it was impossible, my hands started to shake, my voice was gone, and I was so self-conscious of what people would think about what I was doing. Because I didn’t know how to play songs that anybody knew—all I knew how to play were my own songs, and so I had this feeling of having my own chords and my own things that weren’t—I was afraid of being judged as doing nonsense music. But then maybe what the acting did to me was that I got more courage to do what I really wanted to do, even though I had all these fears that were still inside me.

By the time I admitted that I needed a hip operation, I had denied it for so long that it was a breakthrough to suddenly say, “I need this.” I knew I would probably never dance again, but I had no choice. By that time, I just wanted to be normal. I wanted to walk down the street without limping. I couldn’t tie my shoes. I couldn’t put slacks on. I was the farthest thing from a person who ever could dance and do all those extremely incredible extensions and contortions that we do.

I think I'm trying to be as normal as possible, as authentic as possible, and I always try to stay the same way for as long as possible,

Of all the gifts that tennis has given me over the years, the greatest, without a doubt, has been the people I've met along the way: my friends, my competitors, and most of all the fans who give the sport its life.
