A Quote by Martha Graham on vitality, unique, and channel

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. And 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, nor how it compares with other expressions.  It is your
 business to keep it yours, clearly and directly, to keep the channel
 open.... You have to keep open and aware directly to the urge that
 motivates you.  Keep the channel open.
