I suggest great works come most often, when we lose track of our self in the process. In so doing we evolve with the act of creating. There is of course the risk that we get too lost in the process. It is also possible to perfect one s skills through the constant critical-editor. However, creations done in this way generally become repetitive as the critical-editor causes us to use what has worked before and take fewer chances.
Visionary creativity is inherently full of chances.
Lose yourself, or lose the process. Well, there is a middle path. When in the creative act, ignore the editor and flow with the go. Let the process lead you where inspiration will. Then, when your creation has come to life, ask for the editor s help.
