The cloud business taught me a series of lessons I would carry with me for years to come. Perhaps the most important is this: A leader must see the external opportunities and the internal capability and culture—and all of the connections among them—and respond to them before they become obvious parts of the conventional wisdom. It’s an art form, not a science. And a leader will not always get it right. But the batting average for how well a leader does this is going to define his or her longevity in business.
