Justin Higham, British close-up magician and underground card magic legend who fooled both Dai Vernon and Ed Marlo, discusses his new book, "The Intuitive Magician." Justin shares why improvisation, not repetition, is the key to mastering performance. In a broad-ranging conversation, Justin explains his A, B, and C List methodology, the concept of apposite magic, why magicians in 1970s TV detective shows represent the ideal for impromptu performances, and ways to overcome performance paralysis.
