After a very long time, I just paid off the balance of my student loans. A few years ago I transferred it to a 0% interest credit card, and bounced them around a bit. But as of today, it's gone. I also paid off the balance on my American Express card.
I may have been a bit overzealous, and I may have to dip into my credit cards again in the next 2 weeks, but as of right now my only debt is my mortgage, which is no real debt at all.
