I enjoy doing my work, and I don't want to deal with the other things. When you enjoy doing your work so much, why deal with where to show, how to show, what to do? If the artist finds the right gallery which respects their work and gives them that freedom to do whatever they want to do, the artist can focus on his work.
I think artists are really the root of a tree. They can search for truth or reality in their own way, and the gallery can support them - the outside part of the tree, where it is more about reaching the outside world, connecting with the outside world. That is the role of the gallery, no? Why does the artist have to do that?
