I know lots of medical professionals,and most of them do not have balance. It's a passion, a calling, a drive. I asked one ( a busy surgeon) about working less when he was complaining about the crazy hours... and the reply was that he didn't want to sacrifice any of the $$ to bringing another doc into the practice. So there are tradeoffs, I suppose. I know a few that only work 3/4/5 days a week but it's been a conscious choice to take control of their work and personal life.

(warning, major generalizations here)
I think as women we need to look at why we have a tendency to choose partners that aren't really available... whether they work too much, drink too much, play too much, afraid of intimacy or whatever. It's really hard to look at one self, and the part we play in our own choices, but if it's done sucessfully, looking at the roots of things within, it can be transformational in terms of getting what you really want out of life and relationships. Having a partner that is willing to look at thier half of the equation helps, though.
