From one of my favorite writers, this interesting perspective on the inevitable cruxes we face in our creative lives:
The Real Work
by Wendell Berry
It may be that when we no longer know what to do
we have come to our real work,
and that when we no longer know which way to go
we have come to our real journey.
The mind that is not baffled is not employed.
The impeded stream is the one that sings.
