A Woman: What does this mean?

I struggle with being a woman sometimes. I struggle with living in the world that we do, with the way that women are treated. No, this isn't a feminist rant, somewhat the opposite really.

I'm not doing a very good job explaining. Some background first.

I grew up primarily in a rural Ohio town where the majority of people were farmers and college educations were few and far between. Kids grew up, married the girl next door, took over the family business, and at most lived a town away from their parents. If you needed a stereotypical Mid-Western town to look at, where I was from would be perfect.
But I never totally fit in with that culture. I was far too adventurous and forward thinking I suppose. I wanted to travel and live in Italy and dance and go to college far away and do big things.
My dislike of the rural culture I lived in for so long manifested itself in me in that I never wanted to be "just a stay at home mom or housewife." I wanted to do great things with my life and be a scientist and work full time and contribute financially so that I could do awesome things with my money like start a scholarship or build a dance school or something. "Just being a wife and mother" was the last goal I ever had for my life. Yes, I wanted to be a wife and mother, very badly, but I wanted to do that on top of being a great person.

As I have come to college though, my draw to become a wife and mother has been greater and greater. Obviously I am going to finish my degree and work towards getting a full time job when I graduate, and I do really love college and learning things and such, but my heart is often elsewhere. I want to be a wife and mother so badly. It's the strongest desire on my heart. Even when I have a great day at work or in the lab and I feel really fulfilled in the science I am doing, that pull is always there. But the thought of giving any part of career Allyson just doesn't sit well with me. The world tells me that my career should come first and I shouldn't let anything get in the way of that. And my mind tells me that I don't want to be like those women I grew up doing what I considered to pretty much be throwing their life away. So it is a conflict. Between what my heart, and my head, and the world is telling me.

Granted, no decisions really need to be made about this right this moment. I'm not even engaged for pete's sake and I still have three more years of school to do. But I often think about it and it can be very frustrating at times. I realize that the only opinion in all of this that matters is what God is calling me to do and who he is calling me to be. However, I don't think that He has given me a strong answer on this right now. He has simply said "Wait. Wait for the right time. Wait on my perfect timing. And trust." I don't always like doing that though...
