If women are supposed to be less rational and more emotional at the beginning of our menstrual cycle when the female hormone is at its lowest level, then why isn't it logical to say that, in those few days, women behave the most like the way men behave all month long?
This idea of doing it all is the enemy of equality, not the path to do it. It's impossible to do two full-time jobs, and an impossible definition of success is just another way of making women feel like failures... Any definition of success has to include social policies that honor families and men who raise babies as much as women do.
