I've posted this quote before, but it seems a good one for the new year:
"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. 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 it compares with other expression. It is your business to keep it yours clearly and directly-- to keep the channel open."
~ Martha Graham
The great dancer and choreographer also said: "The body says what words cannot," and "Dance is the hidden language of the soul."
I believe these thoughts are keys to figurative sculpture, as well.
