Sometimes creative projects take a very long time to finish. Especially in these modern times, when you can control the flow with new tools and without the same financial pressures of previous times. Storage is cheap. Film stock and processing is not.
But, process changes with technology. The context of creation is the factor. Creativity is not an internal force exerted unto the outer realm. It is a reaction to the outer realm. This is our rebellion against the ambiguous rules set force, by unforeseen energy, into human order.
We try to mimic nature, or in our esteem, to conquer its beauties in words and visuals, to make sense of the chaos. But this chaos is our flame. This chaos is our master.
