The Interactor

 Every day, the funnel collapses around us a tiny bit as we   make our way towards death.  The final destination will   always remain a mystery as anything can happen at any   time to redirect the course of the funnel.

 Yet, it is our initial perspective that attempts to set the   course within the funnel based upon the single output of   our Triaxial Yin-Yang. 

 Analogous to driving, the goal during the journey is to try   not to hit anyone nor anything, while trying not to be hit   by anyone nor anything, and while matching speeds more   or less as we maneuver our way through traffic.

 Also, as with driving, try to make smooth preemptive   course corrections as the further you drift from setpoint,   called "error," the greater the course correction required to   re-achieve the original setpoint.
