What's next?

What is the endgame?  Oh, what to do from here...  Do I continue to grit my teeth, go to work, stamp my timesheet, come home, pay my bills, give attention to the wife, the kids, then wash, rinse and repeat again?  Or do I push for more?  Do I slam myself back to reality; head begrudgingly in the clouds thinking what could have become without a family to feed and shelter?  Perhaps try to rekindle a lost passion for science or art, dormant after an initial self-betrayal to reenlist in the military.  Like so many particles and anti-particles in deep space, surviving for mere microseconds only to destroy each other and completely disappear; are we, as humans, to continue this perpetual dance of insignificance throughout the annals of history?  Entire lifespans winking in and out of existence with no magnum opus to speak of?
