The world is your stage. The play is your playground. Improvise your roles as best as you can. And remember that others are improvising theirs roles too. Work with your fellow actors to create the best performance you can. But remember it’s all an act, and if you aren’t playing a role that works, change the role or change the way you act in it. All the world is an improv stage, and so you get to write the script as you go. Enjoy the performance, you only get one.
