I'm Exhausted!

I've been working hard on my floors for the past three days.  My back aches and my knees are bruised (I tried knee pads but wearing them was more uncomfortable than going without).  I've completed the foyer, about 3/4 of the living room, and now I'm contemplating the hallway.  I'm kinda stuck with the first of FIVE doors I'll have to conquer in the hallway.  It all involves some crazy cuts I'll have to make and I just didn't have the brainpower at 6:30 PM yesterday to tackle it.  I have four days of work ahead of me so I'll have to ponder it again on Monday.
