I am always working on a number of canvases at one time, eight, ten.... I take years to finish them, but I look at them each day... You see the advantage of not working from real life – the apples would be rotten long before I completed my canvas... I find that it is important to work slowly. Anyone who looks at such a canvas will follow the same path the artist took, and he will experience that it is the path which counts more than the outcome of it, and that the route taken has been the most interesting part.
