Secondary BS/BA vs. Graduate School

After graduating and doing practically nothing for an entire year, I have entertained the notion of going back to school for another degree in a different discipline. Normally, one who has a BA would go straight into graduate school, but I am not particularly fond of the idea due to the program limitations in my area and the amount of debt I would be in.

I do, however, feel the odd necessity of going back to college again, since I practically pissed all of it away the first time around. Although I graduated with a high GPA, I learned nothing and did not form any meaningful relationships with professors or peers. Like many others, college was just a mandatory convention that I had to go through, and I did it as quickly and easily as possible.

I'd like to have the chance to do it all over again. I'd like to work hard towards a major that I actually care about and don't feel indifferent towards, and actually take the time to get to know my professors.

However, I am bothered by society's conventions. I'm almost in my mid-twenties, where you're expected to have a good job with a steady salary, not spending another four years in academia. I'd probably be staying with my parents until my late twenties so I could pay off the tuition more easily, which would be disgusting, unless I can find a couple of buddies to share an apartment with.

What would you guys do in my position? Or should I just get some balls and make the most of the degree I've got? Alternatively, the notion of getting a steady job, then going back to school might make more sense, but I can't figure out how people can juggle a real job along with college.

Jam it back in, in the dark.
