Here are some of my favorite provocative questions: What's next? What don't we know? What are we going to do? When did you last create something? What's relevant? What questions should we be asking? What's the most important thing? What would make you a little more uncomfortable? What would be your first move as CEO? What is the world telling you?

A good question is not concerned with a correct answer. A good question cannot be answered immediately. A good question challenges existing answers. A good question is one you badly want answered once you hear it, but had no inkling you cared before it was asked. A good question creates new territory of thinking.
