I have no fear of making changes, destroying the image, etc., because the painting has a life of its own.
When canvas was more difficult to find, and more expensive, artists used to reuse them. A work that did not please, was simply painted over with a new creation. In the creation of great works of art, the vision at the beginning rarely matches the end result.
My life is yet another great work of art. In the act of creation, sometimes I look at my life and decide that this part needs a brighter shade of red, that one a richer blue. I have never had the driving vision of my final goal, so I am free to recreate as I see fit in the moment. I am free to make changes, and destroy the image, because I am there to create anew.
