One other aspect that is not overtly mentioned but I feel is true inside this analogy is that just as actors are not the role they play but they allow parts of their authentic selves show through when they act, neither are we 100% defined by our roles at work. We bring the best part of ourselves to work as leaders but when the curtain goes down (we go home), that is our true selves. So don't let work define you but think of it as only an aspect of yourself that will change over time.
