What is an Actor?

What is an actor? I confess that I have no idea. Perhaps an actor is only as good as their last audition. Or the one that they're preparing for. An actor needs to love themselves because they cannot depend on anyone else's love even though it's set up for them to receive much adulation by having people see them and applaud. They applause is nice but the next day the actor is at the grocery store like everyone else. What aisle is this in? There is no glamour. There are no press junkets. There is no self importance. There is no vanity. There is love. Not false love.
