I am only in debt for my school loans and my car at this point. I got those debts for going to undergraduate and graduate school (although on scholarship in undergrad and fellowship in graduate school, school loans were necessary for all the odds and ends (art supplies, books,etc.) and sometimes living expences too. I have car note because I live in Houston and veryone does :-(
I teach at a private high school. I am fortunate to teach at a school with a heavey focus on the fine arts, and have been allowed to build a New Media Art department here. My budget at work is very well funded, and my base salary is on par with public school teachers. However, I teach an extra class a day, summer school, and do graphic and print work for the school in order to make extra income.
I'm fortunate in that I had a fellowship in graduate school, but I still had to pull about $18,000 in loans between undergrad and grad school and about $10,000 in credit card debt. At 35 I have now paid off the credit card debt and the school loans down to around 10,000, and my note is very low as that my interest rate is about 2%, with payments only about $130/mo. So although for about 8 years after grad school my credit card debt combined with school loan debt did severly impact my free money for art making, it doesn't as much anymore. However, teachers salarys are limited and there is always only just enough to pay bills and make art (but I think that's true of all art teachers, in debt or not).
