The First 25 Years: Gen Y (Now and Forever)
One quarter of everything is everything.
X and Y conserve a circle, so one quarter of everything is everything.
This is easy to see: the first 25 years we observe family and friends, the second 25 years we observe strangers, the third 25 years we observe our selves (as we interacted with family, friends, strangers), the fourth 25 years we observe God (pi) (nature) (reality).
Eventually we figure out, we are always observing the diameter (circumference) of a circle (it is observing us).
