Martha Graham, world-renowned dancer and choreographer, on the most simple and most important rules on staying the course and keeping channels open in creative and innovative endeavors:
There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one you in all time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. the world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open.
From Agnes de Mille’s biography “Martha, the Life and Times of Martha Graham”.
