The readiness is all. Not to be all circular with my Hamlet quotes – but really. . .the readiness is the most significant factor with players. Especially players who are about to do something live. Live-ness depends on readiness in a way that nothing else does. It requires being ready for the thing you’re doing but also for eventualities around that thing.
What happens if someone forgets to set that prop? Only readiness gives you the skills you need to deal with that.
I’ve been developing my company’s first improvised show and there is nothing to be done for the shows but to get everyone as ready as possible. What do we do if someone gives us this? How do we adapt if we get nothing from them? What if it starts to rain?
And we just have to hope that everyone’s ready.
