Career for want to be mom

Hey guys I recently started college, my major right now is Nursing. My heart used to be into it, I was ambitious and I wanted to be a nurse practitioner for the neonatal unit. The thing is i also want to be a mother, I am currently engaged. Honestly I am not an ambitious person, I respect woman who want to earn a college degree and earn money. I just don’t have that mentality and I feel bad that I don’t. I want a simple life, a family and a mother to my children but I know that life is difficult now. I want to help my fiance work. He’s a chef and he works long hour shifts at times, if I were to become a nurse I’d work long hours. I am just really looking for a career where I can graduate fast and start my family but also be able to help my future husband out with the bills and take out my kids with my own money.
