Most will only ever blindly participate in life.  They will accept the boundaries prescribed by society and be sure not to wander outside of them, from birth until death.  

Rare individuals will actually ask questions and seek answers about those boundaries.  These observers will be the first to identify weaknesses in someone's view of reality, yet the last to leave their own cocoon of illusory safety, too disheartened to actually take the steps to make the transformations in their world.  

They are the infinite among us who both observe and participate.  They demolish boundaries they have observed, then proceed to become creators by constantly planning and constructing what they know to be temporary and ever-expanding boundaries.
