In my experience, many of my girlfriends do not want to pursue “anything too serious” during college, in their words, “I am young, I don’t know where I’m going to be next year and I want to keep my options open.” The mutual feelings among college males about their uncertain future, and natural inclination to short-term sexual relationships, creates this liminal space as well. … It seems a career track is problematic for women all around when it comes to marriage and family. Aside from providing extra resources, it works against marriage in general. Although it can be overcome, it seems like the pursuit of a career almost always works as an antagonist to family and the pro-marriage ideas. This is the most frustrating realization I have come to in this course. Have I misconstrued it?
I don't think careers are antagonistic to marriage and family. Indeed, smart women need brain food and challenges, as smart men do. Family is great, but it is not all you will do in a long life. However, delaying marriage in favor of your career throughout your twenties does run a risk of making family impossible.
I would counsel an opposite strategy – you don't want to get too serious about careers now, because who knows what spouses and children the future will bring. Family first, then career, is the more likely strategy to let you "have it all."
