Two years ago, the National Museum of History held the exhibition of paintings for Van Gogh, and I jointed this exhibition. I saw the super famous self-portrait of Van Gogh(Spring, 1887, Otterlo, Kröller-Müller Museum), and I knew that Van Gogh spent much time painting many self-portraits. Why? I think Van Gogh might want to let the people know his spirit, and he can use his representative self-portrait to build the permanent position for himself. Simplified speaking, Van Gogh always did his best for himself, not anyone. Hence, you don't need to disguise yourself, but consider how to do your best.
