To me, the big difference is when you yell cut and then you have to walk over there and deliver a note, it gives it much more import as opposed to "Hey, try that. " It's just much more intimate, I think.
I also learned to tell a story. I think I learned from poetry how to time a story. Poetry's timing, beats and pauses. That white space on the page is as important as the black. The bottom of the page is blackout. It's performance.
