I agree with what you said. Pushing forward to get the project done is so important, cause you're learning by doing. I act, and I'm all about discovery of the character and finding truth. With my first short film film I tried to direct beginning actors like that, forgetting that I've been acting for 6 years. And while editing the film, I looked at the project and thought, no, next time I need to be stronger in how I communicate my vision. I wouldn't have learned that if I gave up on it in the middle.
