"I was bewildered and worried that my entire scale of Values was untrustworthy. I confess that I have a burning desire to be excellent but no faith that I could be. There is a Vitality, A life force, An Energy, A quickening that is translated through you into action and because there is only one of you in all of time, this expression is unique. If you block it, it will never exist through any other medium and it will be lost. The world will never experience it. It is not your business to determine how good it is, nor how valuable, nor how it compares with any other expressions. It is your business to keep it yours clearly and directly. To keep the channel Open. You do not even have to believe in yourself or your work, You just have to keep yourself open and aware, aware to the urges that motivate you, and keep the channel open. No Artist is pleased, There is no true satisfaction whatsoever at any time, there is only a Divine Dissatisfaction, a blessed unrest, that keeps marching us on, making us more alive than all of the others.
