A listener's sigh, grimace, or lack of attention can sometimes be an excellent clue that changes are needed. If I'm not clear about what it is I am making, negative feedback can just stop me midstream from completing the project. It's the listener part of me that feels embarrassed by a choice and sends a mild shudder through my consciousness. I am my own director so there are multiple levels working at the same time, both in performance and in the creative process. I'm kind to myself and let myself try new approaches.
Art is about making decisions.
Failure is a fine teacher. But, I'm also very practical. If a choice is not working, I quickly rescue myself by making new choices. Creating is one of the treasured activities in my life, and I do everything I can to protect my spark of enthusiasm for it. I share with my family and close friends first.
