We play many roles in life.
We are all the main character in our own life, doesn't mean our life is worth watching like a good TV show or movie. Most people live mundane lives and that's okay.
We are part of an ensemble cast at our workplace (unless you are self-employed) and at family gatherings.
We are mere extras when we attend concerts and sporting events.
We might be the villain to our ex-girlfriends or side pieces.
You might be the comic relief to one friend and the "Wise mentor" to another friend.
We may decide to take action and be more of a Director and less of an extra / side character.
