What do fact-checkers, anesthesiologists, U.N. interpreters, and structural engineers have in common? For most of us, the better we perform the more attention we receive. Yet for many "Invisibles"-skilled professionals whose role is critical to whatever enterprise they're a part of-it's the opposite: the better they do their jobs the more they disappear. In fact, often it's only when something goes wrong that they are noticed at all. Millions of Invisibles are hidden in every industry. And despite our culture's increasing celebration of fame in our era of superstar CEOs and assorted varieties of "genius," they're fine with remaining anonymous. David Zweig interviews top experts in unusual fields to reveal the quiet workers behind public successes. Combining in-depth profiles with insights from psychology, sociology, and business, Zweig uncovers how these hidden professionals reap deep fulfillment by relishing the challenges their work presents.
