Consider the third annual How To issue a Swiss Army knife for your career. You’ll rely on the blade—it’s plenty sharp, with expertise on everything from reinventing a brand (Coach (COH) Chief Executive Officer Lew Frankfort) to running a company like an improv group (Twitter CEO Dick Costolo) to reading a financial statement (Oracle (ORCL) President Mark Hurd) to optimizing your personal efficiency (Flickr co-founder Caterina Fake). But what about the corkscrew? It’s tough to predict when you’ll need to know how to kill at parties (Domino’s (DPZ) juggling CEO Patrick Doyle), take a great picture (White House photographer Pete Souza), or beat a conversational dead horse (economist Paul Krugman), but we’ve got you covered there, too. We’ve even got advice for preparing an office for the Apocalypse. Maybe then someone will finally find a use for those little tweezers.
