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 will 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 stay open and aware
to the urges that motivate you.
Keep the channel open.

Martha Graham.
