But let me add a word of caution:taking risks and reinventing yourself also means leaving room for the unexpected, for the perfectly unplanned.And that is particularly true in business and technology.I'm going to ask you three questions.Did you know that the world's biggest hotel company does not own any hotels?Did you know that the world's biggest taxi company does not own any cabs?And the world's biggest news agency does not own any newspapers.Now of course, you know who they are.Who I'm talking about? Of course, Airbnb, Uber, Facebook.Now these companies did not exist a few years ago, and it would have been unthinkable to even ask a question like that.But ever since a little company called Amazon.com,started selling books online, sharing information freely, we have come to expect the unexpected.Disruption -- through technology and market forces -- is the only known variable.And there is only so much in life that you can plan and foretell.I am not suggesting here that you should lean back and relax. Quite the opposite, actually.
