I finally broke through the fog and the wall. I'm thinking that my Writer's Block may have been a simple case of re-working older ideas. There's nothing wrong with older ideas, but I think they fade with time. Or they stay the same, but the writer changes, and they no longer "synch" the way they used to. In any event, I have a new idea, and it's pretty cool. I got a brand new "what if" question, and am trying to answer it. And my character is quite something special. Very excited.
