What I liked most about this book was that it was peppered with anecdotes, puzzles, fascinating facts, silliness, and science. Its premise: “Here’s this mental lock; now here’s how to unlock it.” Its method: a whole raft of pinpricks, seductions, strategies, and whacks ranging from the minute to the mystic to engage your mind and set it on any course other than its usual one. It’s aimed at men in suits and ties, judging from the illustrations, but what it teaches — to think something different than you would ordinarily and take advantage of that new thinking — is a boon to anyone.
