Pick a career and choose a major accordingly. Questions to consider: 1)What do you like doing; 2) Are you planning to supplement a husbands income while raising a family (look for areas where part time jobs abound), OR are you planning to be the primary support of a family while a husband in learning or working in hinuch (look for a job with good pay but some flexibility in hours), OR (and this is highly unlikely) do you know you will not being having children (flexibility in hours are less important)
Majoring in a subject because it is interesting or sound like fun is very expensive. One can always study a subject for fun for free outside of a university.
