If you have ever seen a huge De Kooning or Rothko, you can tell they were painters who were a hundred Percent committed to abstract. There were no partial abstractions, no horizon lines. When I view a painting, I can see if a person was committed. Did they sacrifice? Did they commit to a hundred percent of their talent? Where they engaged to their cause with paint?
In the other arts you can see this as well. In dance for instance, was there complete commitment to the movement, where it was expressed fully? Did the dancer fully commit to making that step? If you have ever danced with a professional or watched a professional dance, they are completely in their bodies and completely absorbed in the movement. It is a beautiful thing.
The question remains how to be fully committed in expression?
