Our guest is acclaimed journalist Bianca Bosker, who tells us that -- when it comes to which topics she chooses to investigate and cover -- she's "obsessed with obsession." Bosker's latest book is "Get the Picture: A Mind-Bending Journey among the Inspired Artists and Obsessive Art Fiends Who Taught Me How to See." She was a security guard at the Guggenheim. She worked in a commercial gallery. She was a studio assistant to an emerging artist. What Hunter S. Thompson did with the Hell's Angels, Bosker does with Art History majors.
