"I painted for 20 years without liking them very much, you know. I burnt them at the end of every year. For 20 years I burnt the whole bunch because I didn't want them to get in the market. And well, sometimes when I was starving, I used to sell one cheap, you know. But I always regretted it because you hate to think of a painting in somebody's house that you don't like well enough, you know."
