  I'd much rather not have to work for other folks..i'm pretty 
unemployable too. I'm pretty sure i qualify for SSI if i wanted to push 
the paper.  F'em. Frankly, we are better off on our own, if we are self 
motivated. Clearly, you are and it makes me happy to see you going for it.
I would note that the ADA represents real recognition that wasn't there 
before, and actually works sometimes.  pf
