I hear yeah Mike. I get up at 0430 and don't get home until around 12 hours later so I am pretty burnt out by the end of the day. Add in a wife, a couple of kids and all that goes along with it, my time at the bench during the week is kinda limited. Try just doing a sub-assembly here and there when you get a chance. Maybe get the 'fuse and/or wings attached the next time you get a chance at the bench. The next day you can do a little putty and sanding. You know the drill...
One thing I have realized since coming back to the hobby a few years ago is that, for me anyway, it's more a "marathon" than a "sprint".

Jeff
