A quote from Martha Graham was shared with me last week -- I'll share it with you here. Whatever is your "expression" you may find this is nice encouragement to keep at it, even when - and especially when - you need to say no to other things in order to say yes to who you are and what you have to offer the world!
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 of time, this expression is unique. And if you block it, it will never exist through any other medium . . . 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.
