“I’ve never taken an assignment,” Stock said when he addressed a gathering of photojournalism students at the University of Texas in Austin’s School of Journalism in 2009. “I’ve always photographed what I wanted to be photographing, and then worried about selling the pictures or doing something with them afterwards. I’ve always shot for myself, and when you’re shooting what you’re interested in shooting, you’re always going to be happy,” Stock told Magnum photographer Eli Reed’s students.
