Software is another one, and probably the more attainable of all of these listed (it's how I am able to mostly afford living here supporting my wife and 1 year old, when neither of my parents went to college, I floundered in college because I had no idea what I was doing, and my grandparents were refugees on one side and blue collar workers on the other), especially with the horror stories I've heard waiting for public or even section 8 housing.
