The lesson here are profound. The plays show us the importance of self-inquiry, as Fitzsimons says. And as van Es points out, our peers play a bigger role than we might guess. For better or worse, the people we work with affect not only our work, but ultimately the people we become.
The reminder that we get to choose who we want to work with (and be around) is important. The people we decide to spend so much time with ultimately impact who we are. Amazing.
