US, you have a different defnition of 'smart'. In my opinion, it is not necessary for only career oriented women to be smart. Ofcourse education helps one build confidence, but not all uneducated people are dumb. And not all career oriented people (both men and women) are smart. I have seen examples. One's smartness depends upon how one can react in a situation: domestic or foreign. I think career should always come second to life, both for men and women.
