Well, I had THAT one figured out all right! Not much else figured, though! LOL!
Sounds like you're grinding your wheels. That happens to me, too. I've found that when I get like that, it's time for me to pull the plug, and get something else on my mind. I realize I need to either recharge my mental batteries, or clear the spinning part of my brain, in order to let a new approach float in. Of course a prayer helps, too. :o)
...I can still do that with the best of them...
I'm sure you can! And when you're done with this, you'll even do *more* with the best of them! Really. And I'll do better, too.
