Up way too late

so it's 4:19 EST Sunday night.  The dregs of the weekend.  These days however there seems to be no end and no beginning of anything- weeks just toss and flow like waves over the ocean.  Sometimes it's hard to tell where one stops and the other starts.  Even days don't always have clear definition nowadays- not when I'm up this late at least.  

I seem compelled to do-- more.  It doesn't seem to matter what or how much I've accomplished, it's never enough for me.  I never feel like I've done enough to satisfy-who?  Who do I wish to satisfy?  Dunno, but it'll never be enough.  As long as i can draw breath I will feel as though I must squeeze every last drop of existence I can out of my time.  

Taking inventory: 3 amazing, intelligent, beautiful, funny, polite children- all with cool names.  1 really busy, big, high-paying, self-important job.  1 small, fairly lucrative, fairly easy company I own and run.  A wonderful Girlfriend (yes, it's capitalized).  Cat, Dog, millions of sparrows, and a hammock.  Not too bad.  Oh yeah, I'm also in an obscure, fascinatingly difficult graduate program that I'm taking because its just as interesting as it is difficult, and because I might just get into a really, really good MBA program with it.  Not that i need more complexity, of course.  

So why can't I sleep?  I guess I just don't want to waste my only down-time with unconsciousness.  Hmmm.
