I read Womenomics: Write Your Own Rules for Success
as suggested by January
Diane Sawyer calls it: "A personal, provocative and challenging book for career women who want less guilt, more life."
While it does deal with women who are working a job outside the home, specifically the corporate world (a planet I left many moons ago), I still found it a satisfying and usable book for my own situation.
One thing I left with was that Dorothy from Oz feeling-- you've had the power all along.
