If I notice that a painting does not work, the motif does not appeal to me, the composition is unbalanced or the colors have been chosen poorly, then I take a long squeegee and remove the color completely in one go.

Often, the rest of paint (still sticking onto the canvas) looks better than what I have previously (sometimes for hours) painted on the canvas.

It is good to know that there is a way out and not every bad picture has to be finished.
