There is always a point in our process where I look around and think, there's no way this is coming together. This is a mess. It isn't going to work. We've failed. This time we can't pull it off.
And every time it does come together by opening night. It's kind of miraculous, really. And at the same time, I'm sure it's something every artist experiences.
By the way, have you read the Improvised Life manifesto? I love this:
You don't need to be an expert to improvise.
Improvising is a practice, like yoga or cooking; the more we do it, the better we get at it.
Creativity can be cultivated. We can learn what we don't know.
We can be afraid to do something, and do it anyway.
