Linchpin [electronic resource] are you indispensable? Seth Godin

But this book is different. It's about you - your choices, your future, and your potential to make a huge difference in whatever field you choose. There used to be two teams in every workplace: management and labor. Now there's a third team, the linchpins. These people invent, lead (regardless of title), connect others, make things happen, and create order out of chaos. They figure out what to do when there's no rule book. They delight and challenge their customers and peers. They love their work, pour their best selves into it, and turn each day into a kind of art. Linchpins are the essential building blocks of great organizations. Like the small piece of hardware that keeps a wheel from falling off its axle, they may not be famous but they're indispensable. And in today's world, they get the best jobs and the most freedom. Have you ever found a shortcut that others missed?"
