If people believe in your material, they will do whatever it takes to get it done. Even if they don't, but you make it as awesome an experience as possible, they will help you reach your goals.
I miss improv. I hate it in a way - watching it, doing it - but only because it's so challenging and nerve wracking. Improv is the only belief system I've ever experienced that directly works on how to be. Just how to be.
