For hundreds of years people have talked about artists having inspiration, but often, some persons would say, write us a symphony or write us a song, on commission. The artists would come up with a masterpiece without waiting to have their muse inspire them.

Things are forgotten and then perhaps picked up again, if we're lucky, it lasts... if not, then it's in the lap of the gods. The important thing was to do some work that I liked and hopefully that some others might also like, whether for a minute, a week, a month, a year.

Most performers don't admit this, because it sounds negative and performers are not supposed to be negative, but when I was on the road, I was lonely.

As I grew up, I was interested in other areas, too, especially literature. It became a major love of mine. Later, it became a difficult choice for me as to whether to major in music or literature. It wasn't until my 30s that I began a profession in music.

I have a great interest in a number of things, perhaps too many. I admire people who seem to concentrate on only one fixed discipline to the exclusion of almost everything else.

With sincere modesty, if there is such a thing, I have never thought of legacy at all. I am always grateful if people like what I have done. A legacy is something no one can forsee.

When people ask me what I do, strangers on a plane, perhaps, I tell them that I think. Thinking is excellent exercise, as much as swimming or jogging.
