Affiliate Marketing Secrets

So I am only 20 years old now with very little college education. I am in the US Army and am currently in Afghanistan. I strongly want to go back to school after I get out of the Army and finish up my degree in Sociology or Psychology. I wanted to work with the FBI, but I don’t see that happening with today’s job market.
So after the Army this is what my resume will look like:
-3 years active duty service in the US Army(1 deployment to Afghanistan)
-SECRET clearance from the US Army good for 10 years as of June 2009
-Fluent in English and Bengali. Also speak French, but not fluently
-Bachelor’s degree in Psychology(or Sociology)
I just want a job where I’ll be able to support myself(be able to afford an apartment, utilities, have enough to eat, gasoline, etc). Do you see me being able to get a job anywhere in the the northeastern United States with these stats? And should I major in Sociology or Psychology? Which would open more doors for me in terms of getting a job that pays enough?
Thanks!

I have worked at 4 Fortune 500 companies during my career. I’ve been with my current company for 3 years and I’ve been promoted twice. A year ago, I became a manager of 4 people. There are aspects of it that I enjoy, like people development. There are aspects of it that I don’t enjoy, like talking about the short comings of my employees during review times and how far I think that they can go with their careers at the company. Writing employee reviews was a draining experience for me. I also like constantly learning. I’m learning how to manage others right now and about corporate policies, but I have less time to learn about my specific discipline. I’m in a ‘hot’ niche of a ‘hot’ (IT) field right now. I wanted the experience of managing others and now I have had that experience (for one year). I’m debating on asking to move to an individual performer role again. While this seems acceptable in my company, I’m not sure how others at other companies would look at it on my resume. My ultimate goal is career marketability. I’m in my early 40’s. I’d like to be able to take what I know and go elsewhere, if circumstances required it, and find a job relatively easily. How might this hurt me, both at my current company and elsewhere in the future?
