When it comes to inventing the future, the most effective leaders are not only teachers, but insatiable learners. Leaders of the future have to be prepared to disrupt themselves, if necessary, should practice "tough-minded optimism," and must be willing to experiment. In any field, leaders who move their organizations forward are the ones who can re-imagine what they’ve always done, refresh and reinterpret the products and services they offer, and unleash bold experiments about what comes next.
