"The first co-working space was opened in San Francisco in 2005. Today, there are over 2500 co-working spaces in existence around the world.

Today, 1.25 billion people use the service. (That's 1 out of every 7 people on planet Earth.) Today, the way we interact with people, the tools we use, and the way we work are all changing at an incredibly rapid pace. This has huge implications for the way we run our careers. In fact, it demands that we utterly reinvent our approach, shifting from a focus on past accomplishments—the 'resum model'—to constant self-iteration, or what I think of as the 'learner's model.'
