People seldom talk openly about their finances. So, here's my net worth from Mint.com from October 2009 until now.
At my worst, I was carrying revolving debt of $9,240 in November 2010. I've paid all that off, and I ended the month of September with my Net Worth above nothing and with zero debt.
Even spending modestly living in New York, it is too easy to enter a "debt spiral". The hardest thing to do but the best thing I ever did was learn how to say Sounds like fun, but I can't afford to do that so I'll pass.
I turned down numerous casual weekday dinner invitations, ended nights a little earlier, and didn't go on weekend getaways. It sucks to have to say no, but I couldn't keep up financially with all of the opportunities that were presented to me.
So my advice from exiting the debt spiral:
Don't be ashamed of your finances and learn to say no. You'll be richer for it.
