“My main difficulty was that I could not paint fast enough. My pictures are all moments of my life – I mean instantaneous visual experiences, generally noted very rapidly and spontaneously. When I begin to paint, it's like leaping suddenly into deep waters, and I never know beforehand whether I will be able to swim. Well, it was Kandinsky who taught me the technique of swimming. I mean that he taught me to work fast enough, and with enough self-assurance, to be able to achieve this kind of rapid and spontaneous recording of moments of life.”
