‘I beg you to be patient with me. It is my greatest wish to learn from you, my superior colleagues, how to produce work of such quality so quickly. I have done my utmost in these past weeks to paint faster, but sadly I was forced to abandon several pictures, because the loss of quality on account of my hurrying was such that I would have disgraced the high standards of our firm. But I will do all I can to improve my poor standing in your eyes. I beg you to forgive me and to be patient a while longer.’
