From the Comments:
“I have that issue of Wired. It’s cover is a reference to my second-favorite TED talk (favorite is TONY ROBBINS). In it, Abrams seems to discover, at the moment he is on stage, one of the key creative aspects of a lot of his work.
“He’s talking about a “Mystery Box” that his grandfather gave him. It’s a package of (probably shitty) magic tricks, but the box itself is beguiling as hell: covered with questions marks, printed with “Mystery Box” and SEALED. He says he will never break the seal on it, because the promise of the mystery is far greater than whatever might be inside it. If I remember correctly, he has a thrilling free-associative moment (the kind you can’t have if your talks are totally structured) in which he realizes that most of his stories have a “mystery box” of one kind or another. When you think about it, the first two seasons of Lost are all about the underground vault as a Mystery Box. Awesome.”
