Sometimes I try to take a nap before shows. That clears my head.
I don't think it makes any sense to try to get anyone to not talk.
Pushing the envelope' sort of implies that you're inside the envelope with everyone else, and you're trying to find the edges on the outsides.
You have to be able to do a bunch of things at once, and not think about things you're not doing while you're doing other things. You have to be disciplined about not trying to do everything, all at the same time. It's hard and fun.
I think you have to try and fail, because failure gets you closer to what you're good at.
