I got a crappy entry-level job in an office, enrolled in college part-time, I was making $ 18,100/year at my full-time job, I was paying $500/month in rent, $150/month for a crappy car, and $550/per each college class. I did not qualify for student loans since I was making too much money.
So I took a part-time job, on top of my full time job, so that I could go to school at night 3 times a week.
It took me 8 years to graduate with my BS in Business (minor in CS), I went on for my MBA... to make a long story short it all paid off, I became a VP and develop a career mixed between being an executive and being an entrepreneur.
Chances are that my "recipe" won't work out for you, the common thread between my stories and other stories that I have heard is:
* work hard
* make your own mistakes (I have made a few, I didn't list them above)
* iterate fast
* when failing, pick up the pieces and continue
Not all that wanders are lost.
You could try the entrepreneurship route.
