No one worries about the cost of career stress on a man's marriage.  I wonder why that is? (Actually, I think I know: the subtext  of these questions showing concern for women is, women shouldn't be out there doing "men's work."  It is sort of like when your mother is saying, are you going out wearing that? Or I am worried about...  The subtext is: I don't like what you are doing.  Stop doing it and do what I want.)
Guess what: life is stressful for men and women.  Women need to stop listening to what people think about them going into the world.  Will they be happy?  Will it make them unattractive? Will they be able to have it all? Who knows?  Who cares?  We are human beings.  Sometimes stuff will work out for us; sometimes it won't while we go out into the world and do neat things. 
(I liked the online comment the other week about women "invading" men's jobs.  What are you, Poland?)
 We are not going back into the kitchen.  Deal with it.
