Sometimes I am happy and sometimes not. I am, after all, a human being, you know. And I am glad that we are sometimes happy and sometimes not. You get your wisdom working by having different emotions.
I'm free from holding personal anger because I can express what I want through my music.
We don't live by just sleeping and eating. We need pride and dignity in our lives. Work gives you that.
I always believed that my work should be unfinished in the sense that I encourage people to add their creativity to it, either conceptually or physically. Back in the 1960s, I was calling for 'Unfinished Music,' number one, and number two, with my artwork - I was taking unfinished work into the gallery. And that's how I was looking at it.
