Where do I go from here?

I'm 24 with a top-notch education, a wonderful boyfriend, and a great job that could easily become a career. I'm living "the dream", but I don't think I want it. I don't think this is my dream. And I have no idea how to figure out what my dream is, or how to go about chasing it down.

I know how I got here. I basically fell into this life through a combination of luck, opportunity, intelligence, and a complete lack of goals. I took a lot of math and science classes in high school because these subjects were easy for me. This led me to Harvey Mudd College where I majored in physics because... Well, because it was more interesting than math and easier than chemistry. It had fewer requirements than any of the other majors which meant more time for electives.

By my senior year I was tired of it. Quantum mechanics frustrated me. General relativity confused me. Electromagnetism made me want to bang my head against a wall, which I actually did at least once a week. I hated everything I was studying and dealt with it by drinking far too much and smoking more. I remember thinking that if I had to do it over again, I'd major in history or literature. Because what's the point of understanding the universe if we can't even understand each other? With only one semester to go, I realized that the best option was to stick it out. So at 21 I graduated with a BS in physics, and the only thing I knew was that I didn't want a PhD in it.

After months of job hunting, applying, interviewing, and being rejected, I discovered a small company that did cognitive modeling research. Cognitive modeling is equal parts computer science, artificial intelligence, and psychology. It seemed like a good fit. At least I was shifting towards understanding other people while still using my very expensive education.

So that's the field I'm in now, though my job is a bit less psychology and a bit more computer science. Everyone I work with has an MS or a PhD in some field related to this. They're starting to pressure me to get one, too. Except I don't want another degree. The idea of going back to school repels me. I don't even know what I would study. I love to read. I love learning about people. So I'd be drawn, once again, to history or literature. Neither of these degrees is exactly related to my job. Psychology or sociology would be a good compromise. Do I want to base my career on a compromise?

The problem really is that I have a dream job, but it isn't my dream job. I have great colleagues, flexible work hours, interesting problems to solve, and the freedom to pursue a variety of different types of work. But I'm not passionate about it.

So where do I go from here? Do I keep my wonderful job, with it's steady pay and benefits? Do I look for something else to do? Do I bite the bullet and head back to school, pushing off other dreams of a house and kids?

The only solid answer I've really gotten is "start a blog". So that's what I'm doing. This is my place to figure out who I am and what I want out of life. I don't know what exactly will end up in here. I don't know if anyone will even read it. But I'm going to try and stick to it. Hopefully I'll figure out my life in the process.
