Now that is an interesting question!
I would say that there are times when we do both but the place we need to be is living our own lives. Delivering a performance means we are living our lives for someone else, trying to meet their expectations of who they think and want us to be. When you deliver a performance, you are giving yourself away and basically you lose… you lose living the life you are meant to live.
Focus on living your own life and quit delivering performances!
