You don't have to be famous to achieve your self worth. Those who count already know that you are a special and gifted artist. Japan may not be there yet in its full appreciation and understanding of the whole concept of art. Just think of yourself as one of the pioneers who will help teach everyone the beauty of creativity and open a wider door to the value and diversity that it brings. Unfortunately people think of the old art as being the true art. In time people will gradually expand their appreciation.....just be patient and continue to press on!
