open it wide , baby

There is a vitality, a life force, a quickening that is translated
through you into action, and because there is only one of you in all
time, this expression is unique.

If you block it, it will never exist through any other medium and be
lost. The world will not have it. It is not your business to determine
how good it is; nor how valuable it is; nor how it compares with 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 have to
keep open and aware directly to the urges that motivate you.

Keep the channel open. No artist is pleased. There is no satisfaction,
whatever at any time. There is only a queer, divine dissatisfaction; a
blessed unrest that keeps us marching and makes us more alive than the
others.

Martha Graham (in a letter to Agnes DeMille)
