That is why art, including the fine arts and the performing arts, can be such a powerful spark for creativity. For centuries, the rich and powerful have sought art in their lives. Generally, when the rich and powerful want something, it is very much worth having. In the practical world of business and commerce, we sometimes make the mistake of dismissing art as frivolous. It is not.
Art is a rich source of raw material for solving problems and creating new ideas.
