It may be a long shot, but worth a try: what about applying for a sabbatical? There may not be a formal program, but it might be something to explore. You never know. You could save up some $ and see if you can get a year off; maybe something like Trekhawk is talking about. There are some companies that offer this, or are open to it. If it is just the time, it might be worth it to the company. It's a way to keep good workers from getting burned out. You might start a trend!
I didn't mean to suggest that working for oneself is a piece of cake, by any means. I have just noticed over time (and there is some research to support this) that women are less willing to put up with the vagaries of the corporate world (which I think is a good thing). For example, I have a sister who lives in a rural area and does editing for a couple of publishers. The work can be variable, and she does a lot of other money-making things. There are also a number of local voluntary simplicity groups in many areas that can serve as a support group; I think the website associated with the Dominguez book lists some. Duane Elgin's book is also good, and has support groups.
The bicycle is the most civilized conveyance known to man. Other forms of transport grow daily more nightmarish. Only the bicycle remains pure in heart. ~Iris Murdoch, The Red and the Green
