Where'd my motivation go?

I'm not even sure where to start on this one.  I've pretty much lost any shred of motivation for a few things, most notably working out and doing P90X.  The alarm goes off in the morning and it's snooze after snooze for a good 45 minutes.  Even getting home after work and by the time dinner is done it's 7pm or sometimes even 8.  There's always a constant battle with laundry, dishes, clutter around the house... more things I have no motivation for.  Maybe my feeling of lack of accomplishment at work is carrying over.  Who knows.
