"Drawing for me has never been a case of therapy because I was shy, or not outstanding in physical activities, or anything else. It was a compulsion. I carried a sketchbook day and night, because I could not stop drawing. To sell a sketch was a pleasure, because it meant a little less economic worry and more freedom to explore. But if I had not sold, I still would not have stopped."
"To me line is something which one can explore endlessly, and which keeps me in a constant feeling of excitement and adventure. I know I shall never live long enough to say and do all I want in line. I can only hope to get up each day, bursting to push the exploration a little further. But line is useless if one has nothing to say with it. The artist must be driven with the desire to express something, and use any device to achieve it. He must be perverse. Everybody will want to mold him to their pattern. But in the end he has to satisfy himself — or spend his life trying to please other people."
"If satisfaction with one’s work creeps in, the time has come to give up and take to prostitution. A sure sign that there is still hope is when one is miserable at not having met one’s own demands."
"The hand is feeble and the artist has still to express with exactitude what his brain conjures up."
