That's a really tough question.
I'm not sure whether I would want to be good looking or not, since being good looking would probably result in receiving more attention, which I would not currently appreciate.
On the other hand, if I were better looking, perhaps I would have more confidence and with more confidence I might be less anxious and then I might tolerate such attention better.
As for intelligence, well, that could also be a curse or a blessing.
Even if the options were "Good looking, no anxiety issues and stupid" or "Very intelligent, ugly, with SA" the decision would still be a difficult one. I'd probably opt for the former though; if you're stupid, you probably wouldn't know what you were missing anyway.
