With watercolour, you can pick up the atmosphere, the temperature, the sound of snow shifting through the trees or over the ice of a small pond or against a windowpane. Watercolour perfectly expresses the free side of my nature.

Don't overdo it, don't underdo it. Do it just on the line.

I wanted to get it all down, maybe out of my system. I wanted to be able to say, Everything's possible-if you believe and can get excited.

To have all your life's work and to have them along the wall, it's like walking in with no clothes on. It's terrible.

I have a good friend, Rudolf Serkin, the pianist, a very sensitive man. I was talking to him one day backstage after a concert and I told him that I thought he had played particularly sensitively that day. I said, "You know, many pianists are brilliant, they strike the keys so well, but somehow you are different." "Ah," he said, "I don't think you should ever strike a key. You should pull the keys with your fingers."

What you have to do is break all the rules.

If somehow I can, before I leave this earth, combine my absolutely mad freedom and excitement with truth, then I will have done something.
