Whatever you decide to do, do it before you get married and have kids.
I know you're not in a relationship now, but so many people feeling like you do tend to view a relationship/marriage as the solution to "I don't know what to do with my life." Ask me how I know, heh. That will definitely settle a few things for you, by means of removing options.
I envy you. I wanted to travel, or at least move away somewhere and be independent for a while. But I got guilted into being a good girl, staying home, getting a job and settling down because I had parents who would've been "heartbroken" if I had been more adventurous.
What tora says is absolutely true. Unless you're in a highly specialized field, it does not matter what your degree is, just that you HAVE one. My Associates is in liberal arts. Nothing wrong with that.
