"In the good old twentieth century, you could reinvent your company, product category or industry once, and then go for a decade before doing anything especially innovative again. That doesn't work anymore. The world has changed, and more importantly, change itself has changed. [...] In the past, stability and change were two contrasting states: when you achieved stability, you did so despite change. Today change itself has become an integral part of stability: today you can achieve stability only by embracing change as a continuous and permanent state. It used to be, you could find something you do well, learn how to do it, and just keep on doing it. Not anymore. In the past, reinvention was an option. Today it is an imperative."
