Not sure if you are saying you are lame at improv or you don’t like the analogy? Regardless, in an improv script, the actors are given a set of parameters and then they make choices on how to play it and each person's choices affect the choices of the others. I would say it makes a person less subject to fate but at the same time, less in control of the outcome as the free will of others plays a huge role. That was a good question. It also highlights that the only things we can fully control are our own reactions and attitudes, which is what the serenity prayer is about. https://medium.com/channspirations/the-serenity-prayer-df758d99c956
