Quote:

"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 do not 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." -Martha Graham

This is one of my favorite quotes.  Martha Graham was a modern dancer and she was probably speaking of dance specifically, and certainly of creativity, but it applies just as well to emotional expression.  And to a way of being.  I spent my early years with the channel closed.  As an adult, I'm trying to "keep the channel open" in every way possible.
