Been there. Destroyed my credit right out of the gate when I tried to run a web development firm in 1997 on student credit cards. Was threatened with eviction twice, and eventually was forced to move. Was fired and subsequently sued for $millions from/by a dot com in 1999 at a time when I literally had a negative account balance. I had dropped out of school to pursue my ambitions, so I had no degree to fall back on in order to secure a well-paying "job".

Disclaimer: the following is intended to be inspirational, not boastful.

13 years later, I am partner in a profitable ecommerce enterprise, after having put a startup success notch in my belt in 2004. My credit score is pushing 800, and I no longer even think about money.

My point is, your life isn't over, no matter how much it seems that way. It doesn't take long to bounce back.
