You cannot be firmly certain about anything. You can only have enough courage and strength to do what you consider to be right. Maybe it turns out that was wrong, but still you would have done his, and it is most important.
Irving StoneI cannot draw a human figure if I don't know the order of his bones, muscles or tendons. Same is that I cannot draw a human face if I don't know what's going on his mind and heart. In order to paint life one must understand not only anatomy, but what people feel and think about the world they live in. The painter who knows his own craft and nothing else will turn out to be a very superficial artist.
