Virtuous woman = superwoman ?

This is the book I am currently reading. I've always wondered about the Proverbs 31 woman in the bible. She is able to somehow manage both household AND work very well, AND on top of that seems to also do volunteer work. Her husband and children "rise up and call her blessed". Does a person like this really exist? I bought the book to find out. After all, who doesn't like to be praised by their husband and children?

I've heard that Chinese women from the Hakka clan are known to be capable both in and out of the house, at least in the old days. I'm half-Hakka (my father is) so does that make me capable only either at home or at work??!
