I've painted for a very long time, but I don't get tired or bored by it; I love to do it. If I don't paint one day, I don't feel well physically or mentally. My eyes bother me when I don't paint. But when I paint a full day, I feel satisfied and everything seems to be OK. I would never stop, never retire. I don't see how people can retire; I don't understand that. My brother Moses died while he was painting. He was actually working on a painting, and the last words he said were to the model: "Phoebe, don't frown." Then he died. He worked to the very last minute.
