Mistakes can't be erased, but they move you from your present position.

My freedom consists in my moving about within the narrow frame that I have assigned myself for each one of my undertakings.

I can never accomplish what I want - only what I would have wanted had I thought of it beforehand.

Somehow don't be bored, but if you must, use it in action. Use its destructive potential.

When I am halfway there with a painting, it can occasionally be thrilling... But it happens very rarely; usually it's agony... I go to great pains to mask the agony. But the struggle is there. It's the invisible enemy.

I don't go into the studio with the idea of 'saying' something. What I do is face the blank canvas and put a few arbitrary marks on it that start me on some sort of dialogue.

Abstract means literally to draw from or separate. In this sense every artist is abstract for he must create his own work from his visual impressions. A realistic or non-objective approach makes no difference. The result is what counts.
