Web developers did it to bring together multiple sources onto one internet page. Musicians and DJs followed by sampling songs from different genres to create new music. Now everyone is doing it: at work, at the weekends, in business. It's time for you, your business and your career to cash in on the mash-up. The days of being defined by a single job title are vanishing. In the new economy our core competences are increasing; we've gone plural, perfecting multiple skills that reflect the multiple talents we have to offer. Today we are witnessing the rise of the workplace 'mash-up' and the smart guys are creating new revenue streams with each new skill they add. At the same time they're making themselves highly desirable, better paid and carving out more fulfilling and authentic work lives. Mash-up! shows you how you can join in the game.
