I do freelance photography and video production. I have a mortgage loan. Much of my debt comes from purchasing photography and filmmaking gear to create orignal artistic work as well as client work to pay bills and live. Being a creative in a corporate city as Houston can be a challenge considering arts and creative services aren't respected as valuable as in other major metropolitan cites.
Debt affects my art practice in that it causes me to constantly have to decide between spending my time creating new creative work or focusing on making money to pay off debt.
Buying camera equipment, software, getting laid off three years ago, home mortgage, etc.
