Simple: Any high achievement includes stress or else everyone would do it.
There is no question that women cannot compartmentalize her feelings and emotions as well as a man does.
They invariably start treating their husband as another competitor to be defeated and even the smallest decision becomes a battle of wills that she cannot afford to lose.
Besides, having a high achieving woman in the house means most of one of your salaries is going to go for daycare so that strangers raise her kids while she is out achieving something worthless in comparison....
Talking from experience? :-) Successful women would not ordinarily have time to get into the petty battles of the wills.
