Not sure I agree that men have a pressure to succeed that women don't. My wife faced plenty of this pressure in her software career: as a point of professional pride, as a prerequisite to career advancement, and because her family raised her to be financially independent. Stuff you cite was all stuff my wife went through as much as I.
And I question the generalization prima facie, as it does not reflect the experience of me or the women I'm close to. Unless there's data to support it?
